God is Omnipotent, He has All Power. 

God is all-powerful. There is nothing that He cannot do.

Since God has absolute, infinite Power, He can do what is best for you.

 Gen. 18:10-14

[10] And he said, I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard it in the tent door, which was behind him.
[11] Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women.
[12] Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?
[13] And the LORD said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old?
[14] Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.

Jer. 32:15-19

[15] For thus saith the LORD of hosts, the God of Israel; Houses and fields and vineyards shall be possessed again in this land.
[16] Now when I had delivered the evidence of the purchase unto Baruch the son of Neriah, I prayed unto the LORD, saying,
[17] Ah Lord GOD! behold, thou hast made the heaven and the earth by thy great power and stretched out arm, and there is nothing too hard for thee:
[18] Thou shewest lovingkindness unto thousands, and recompensest the iniquity of the fathers into the bosom of their children after them: the Great, the Mighty God, the LORD of hosts, is his name,
[19] Great in counsel, and mighty in work: for thine eyes are open upon all the ways of the sons of men: to give every one according to his ways, and according to the fruit of his doings:

Gen. 1:1-11

[1] In the beginning God created the heaven and the earth.
[2] And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
[3] And God said, Let there be light: and there was light.
[4] And God saw the light, that it was good: and God divided the light from the darkness.
[5] And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
[6] And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
[7] And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.
[8] And God called the firmament Heaven. And the evening and the morning were the second day.
[9] And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so.
[10] And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good.
[11] And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.

Eph. 3:14-21

[14] For this cause I bow my knees unto the Father of our Lord Jesus Christ,
[15] Of whom the whole family in heaven and earth is named,
[16] That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;
[17] That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love,
[18] May be able to comprehend with all saints what is the breadth, and length, and depth, and height;
[19] And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.
[20] Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us,
[21] Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.

 Psa. 103:19

[19] The LORD hath prepared his throne in the heavens; and his kingdom ruleth over all.

Psa. 115:1-3

[1] Not unto us, O LORD, not unto us, but unto thy name give glory, for thy mercy, and for thy truth's sake.
[2] Wherefore should the heathen say, Where is now their God?
[3] But our God is in the heavens: he hath done whatsoever he hath pleased.

Isa. 46:9-11

[9] Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me,
[10] Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:
[11] Calling a ravenous bird from the east, the man that executeth my counsel from a far country: yea, I have spoken it, I will also bring it to pass; I have purposed it, I will also do it.
