Romans 4:19-23King James Version (KJV)
19 And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sarah’s womb:
20 He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
21 And being fully persuaded that, what he had promised, he was able also to perform.
22 And therefore it was imputed to him for righteousness.
23 Now it was not written for his sake alone, that it was imputed to him;
Abraham didn’t focus on his own impotence and say, “It’s hopeless. This hundred-year-old body could never father a child.” Nor did he survey Sarah’s decades of infertility and give up. He didn’t tiptoe around God’s promise asking cautiously skeptical questions. He plunged into the promise and came up strong, ready for God, sure that God would make good on what he had said. That’s why it is said, “Abraham was declared fit before God by trusting God to set him right.” But it’s not just Abraham; it’s also us! The same thing gets said about us when we embrace and believe the One who brought Jesus to life when the conditions were equally hopeless. The sacrificed Jesus made us fit for God, set us right with God.
