I AM THE LORD, THE GOD of all mankind; is there anything too hard for ME?
Jeremiah 32:27 (TLB)

GOD told Abraham, “As for Sarai your wife, you are not to call her Sarai any longer, because her name is to be Sarah. I will bless her. Furthermore, I will give you a son from her. I will bless her, so that nations, kings, and people will come from her.” Abraham fell to the ground, laughed, and told himself, “Can a child be born to a 100-year-old man? Can a 90-year-old Sarah give birth?”
Genesis 17:15-17 (ISV)

THE LORD asked Abraham, “Why did Sarah laugh? Does she doubt that she can have a child in her old age? I AM THE LORD! There is nothing too difficult for ME. I’ll come back next year at the time I promised, and Sarah will already have a son.”
Genesis 18:13-14 (CEV)

Then GOD did as HE had promised, and Sarah became pregnant and gave Abraham a baby son in his old age, at the time GOD had said.
Genesis 21:2 (TLB)

JESUS looked straight at them and said, “There are some things that people cannot do, but GOD can do anything.”
Matthew 19:26 (CEV)
