Hebrews 11:19

Accounting that God was able to raise him up, even from the dead: faith put this into Abraham's thoughts in his reasonings about this trial between the temptation and God's power, and influenced him to conclude and determine under it. That since God could raise him from the dead to perform his promises, he would sacrifice him to obey God's command. This faith grew from what God had done, in giving him Isaac from his own dead body, and Sarah's dead womb, Romans 4:17. God's almighty power to raise from the dead answered all the difficulties in the trial. If God command it, who can raise from the dead, this can be no murder; for he can either prevent or recover. Promises should not fail, though Isaac was sacrificed; for God would raise him up and accomplish them. As to arguments from natural affection: Shall a child be dearer to me than a God, who quickens me, and can raise him from the dead? Since God can do this, what difficulties can he not overcome? Hence is this principle so often revealed and repeated to be a sure prop to a Christian's faith throughout the gospel. From whence also he received him in a figure: his generation was a kind of resurrection from the dead, and so was his restitution to Abraham, for in Abraham's account he was dead, his hand being lifted up to kill him, when the angel stops the execution, Genesis 22:11,12. From the altar he carrieth him back as a trophy and reward of the victory of his faith, in such a manner as one risen from the dead, and an eminent signal of his victory over this temptation. Abraham had a figure of the resurrection in his son, and an earnest of a far more glorious resurrection in Christ.
