Hebrews 11:1, 17, 19

Faith shows the reality of what we hope for; it is the evidence of things we cannot see.

It was by faith that Abraham offered Isaac as a sacrifice when God was testing him. Abraham, who had received God’s promises, was ready to sacrifice his only son, Isaac

Abraham reasoned that if Isaac died, God was able to bring him back to life again. And in a sense, Abraham did receive his son back from the dead.
