“If God’s promise is only for those who obey the law, then faith is not necessary and the promise is pointless. For the law always brings punishment on those who try to obey it. (The only way to avoid breaking the law is to have no law to break!) So the promise is received by faith. It is given as a free gift. And we are all certain to receive it, whether or not we live according to the law of Moses, if we have faith like Abraham’s. For Abraham is the father of all who believe. That is what the Scriptures mean when God told him, “I have made you the father of many nations.” This happened because Abraham believed in the God who brings the dead back to life and who creates new things out of nothing. Even when there was no reason for hope, Abraham kept hoping—believing that he would become the father of many nations. For God had said to him, “That’s how many descendants you will have!” And Abraham’s faith did not weaken, even though, at about 100 years of age, he figured his body was as good as dead—and so was Sarah’s womb. Abraham never wavered in believing God’s promise. In fact, his faith grew stronger, and in this he brought glory to God. He was fully convinced that God is able to do whatever he promises. And because of Abraham’s faith, God counted him as righteous. And when God counted him as righteous, it wasn’t just for Abraham’s benefit. It was recorded for our benefit, too, assuring us that God will also count us as righteous if we believe in him, the one who raised Jesus our Lord from the dead. He was handed over to die because of our sins, and he was raised to life to make us right with God.”
‭‭Romans‬ ‭4:14-25‬ ‭NLT

Abraham, being an elderly man, approximately 100 years old, should have, naturally speaking, been incapable of fathering a child. However, God, supernaturally, made him capable. This was an act of God! The same was true of his wife Sarah. She was 90 years of age. Have you ever known, personally,  a 90 year old woman who got pregnant and had a baby? I haven't. It would be considered a miracle. Indeed, it would be. In the natural, it is impossible. With God, it is possible.
We, too, must recognize that the only way we can be "born again" (John 3:1-7) is through supernatural impartation. We are dead in sin (Ephesians 2:1). Only Jesus can, by his power, make our sinful, dead spirit alive again. Take a moment to praise Him right now!!!
