If Jesus has already returned, what is He doing now?

He is not idle. He is indeed very active.

1) He is reigning as KING of kings and LORD of lords.

He returned to earth and established a literal, earthly kingdom. We presently live during a little season when the enemy has been loosed from his pit,  but Jesus has not turned His rule over to him. Satan has no Authority and no rightful place on the earth or heaven anymore. He is being allowed to deceive people.   Believe the Word of God 100% and you will not be deceived. Believe his lies and you are deceived.

Reject Satan's lies and believe and receive God's truth!

Believing Satan's lies brings bondage.

2 Tim. 2:24-26

[24] And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient,
[25] In meekness instructing those that oppose themselves; if God peradventure will give them repentance to the acknowledging of the truth;
[26] And that they may recover themselves out of the snare of the devil, who are taken captive by him at his will.

John 8:32-36

[32] And ye shall know the truth, and the truth shall make you free.
[33] They answered him, We be Abraham's seed, and were never in bondage to any man: how sayest thou, Ye shall be made free?
[34] Jesus answered them, Verily, verily, I say unto you, Whosoever committeth sin is the servant of sin.
[35] And the servant abideth not in the house for ever: but the Son abideth ever.
[36] If the Son therefore shall make you free, ye shall be free indeed.

Rev. 19:11-16

[11] And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
[12] His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
[13] And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
[14] And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
[15] And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
[16] And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS. 

2) He is holding the universe together. 

Col. 1:10-17

[10] That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God;
[11] Strengthened with all might, according to his glorious power, unto all patience and longsuffering with joyfulness;
[12] Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light:
[13] Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son:
[14] In whom we have redemption through his blood, even the forgiveness of sins:
[15] Who is the image of the invisible God, the firstborn of every creature:
[16] For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
[17] And he is before all things, and by him all things consist.

Heb. 1:1-3

[1] God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
[2] Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
[3] Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high;

3) He is resting at the right hand of God the Father in the heavenlies.

When the priests performed their duties in the tabernacle and later the temple, they were never able to sit down. There were no chairs in the Holy place or in the holy of holies. They could not sit because their work was never finished because it was impossible for the blood of bulls and goats to take away sin. The sacrifice of Jesus Christ, the perfect Lamb of God ended all of that. Jesus was able to sit down. He was and is our great high priest!

Heb. 10:1-14

[1] For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
[2] For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.
[3] But in those sacrifices there is a remembrance again made of sins every year.
[4] For it is not possible that the blood of bulls and of goats should take away sins.
[5] Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:
[6] In burnt offerings and sacrifices for sin thou hast had no pleasure.
[7] Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.
[8] Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law;
[9] Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.
[10] By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
[11] And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins:
[12] But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
[13] From henceforth expecting till his enemies be made his footstool.
[14] For by one offering he hath perfected for ever them that are sanctified.

4) He is interceding for us.

Rom. 8:20-31

[20] For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope,
[21] Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
[22] For we know that the whole creation groaneth and travaileth in pain together until now.
[23] And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
[24] For we are saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for?
[25] But if we hope for that we see not, then do we with patience wait for it.
[26] Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
[27] And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
[28] And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
[29] For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
[30] Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
[31] What shall we then say to these things? If God be for us, who can be against us?
[32] He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?
[33] Who shall lay any thing to the charge of God's elect? It is God that justifieth.
[34] Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.

5) He is meeting with us when we gather to worship Him.

Matt. 18:18-20

[18] Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven.
[19] Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven.
[20] For where two or three are gathered together in my name, there am I in the midst of them.

6) He is drawing men to Himself and He is saving them when they call upon Him.

John 6:44

[44] No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.

Rom. 10:9-13

[9] That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
[10] For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
[11] For the scripture saith, Whosoever believeth on him shall not be ashamed.
[12] For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
[13] For whosoever shall call upon the name of the Lord shall be saved.

7)  He is longing for you to be with Him!

What has been called The Lord's Prayer is actually the Lord's instruction, teaching us how to pray. Part of that prayer is asking for forgiveness of sins and of course Jesus would never need to do that because He never committed a sin.

The actual Lord's Prayer is recorded in John chapter 17 and you can read it below!  We get to see what was on  the heart of Jesus as he was preparing to go to the cross.  He prayed for us to be one  with him, that we would have unity with one another, and  it is evident that He was longing for us!  He prayed that  we would be with him! The prayers of Jesus are always answered!  If you are one of his  disciples (followers) you are going to be with Him someday. 

John 17:1-26

[1] These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee:
[2] As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him.
[3] And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
[4] I have glorified thee on the earth: I have finished the work which thou gavest me to do.
[5] And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.
[6] I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word.
[7] Now they have known that all things whatsoever thou hast given me are of thee.
[8] For I have given unto them the words which thou gavest me; and they have received them, and have known surely that I came out from thee, and they have believed that thou didst send me.
[9] I pray for them: I pray not for the world, but for them which thou hast given me; for they are thine.
[10] And all mine are thine, and thine are mine; and I am glorified in them.
[11] And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are.
[12] While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.
[13] And now come I to thee; and these things I speak in the world, that they might have my joy fulfilled in themselves.
[14] I have given them thy word; and the world hath hated them, because they are not of the world, even as I am not of the world.
[15] I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil.
[16] They are not of the world, even as I am not of the world.
[17] Sanctify them through thy truth: thy word is truth.
[18] As thou hast sent me into the world, even so have I also sent them into the world.
[19] And for their sakes I sanctify myself, that they also might be sanctified through the truth.
[20] Neither pray I for these alone, but for them also which shall believe on me through their word;
[21] That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
[22] And the glory which thou gavest me I have given them; that they may be one, even as we are one:
[23] I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
[24] Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.
[25] O righteous Father, the world hath not known thee: but I have known thee, and these have known that thou hast sent me.
[26] And I have declared unto them thy name, and will declare it: that the love wherewith thou hast loved me may be in them, and I in them.
