Num 11:23 And the LORD said to Moses, “Is the LORD’s hand shortened? Now you shall see whether my word will come true for you or not.”
Genesis 18:14 Is anything too hard for the LORD?
Isaiah 50:2 Why, when I came, was there no man; why, when I called, was there no one to answer? Is my hand shortened, that it cannot redeem? Or have I no power to deliver? Behold, by my rebuke I dry up the sea, I make the rivers a desert; their fish stink for lack of water and die of thirst.
Isaiah 59:1 Behold, the LORD’s hand is not shortened, that it cannot save, or his ear dull, that it cannot hear
Micah 2:7 Should this be said, O house of Jacob? Has the LORD grown impatient? Are these his deeds? Do not my words do good to him who walks uprightly?
Luke 1:37 For nothing will be impossible with God.”
Ezekiel 24:14 I am the LORD. I have spoken; it shall come to pass; I will do it. I will not go back; I will not spare; I will not relent; according to your ways and your deeds you will be judged, declares the Lord GOD.”
Numbers 23:19 God is not man, that he should lie, or a son of man, that he should change his mind. Has he said, and will he not do it? Or has he spoken, and will he not fulfill it?
God had not suddenly become weak or limited. God had resources that Moses knew nothing about. God would meet Israel’s need in a completely unexpected way. (Guzik)
Is the divine power diminished? What has not God done to convince mankind that his power is always unlimited? And yet man is still ready to fall into the weakness of thinking that there are circumstances in which the power of God cannot afford relief or deliverance. (Benson)
Even true and great believers sometimes find it hard to trust God under the discouragements of second causes, and against hope to believe in hope. God here brings Moses to this point, The Lord God is Almighty; and puts the proof upon the issue, Thou shalt see whether my word shall come to pass or not. If he speaks, it is done. (Henry)
Is there any limit to what God can do? NO. Is there a limit to what we think God can do? YES. I wonder why it is that we put limits on what God can do. He can do all things. Nothing is impossible for God. Absolutely Nothing! He is the all-powerful and all-knowing Creator of everything seen and not seen. He can do more than we ask and much more than we can imagine.
