Heidelberg Catechism Question 14
Can another creature—any at all—pay this debt [of sin] for us?
Ezekiel 18:4, 20 – For everyone belongs to me, the parent as well as the child—both alike belong to me. The one who sins is the one who will die…
The one who sins is the one who will die. The child will not share the guilt of the parent, nor will the parent share the guilt of the child. The righteousness of the righteous will be credited to them, and the wickedness of the wicked will be charged against them.
Hebrews 2:14-18 – Since the children have flesh and blood, he too shared in their humanity so that by his death he might break the power of him who holds the power of death—that is, the devil— and free those who all their lives were held in slavery by their fear of death. For surely it is not angels he helps, but Abraham’s descendants. For this reason he had to be made like them, fully human in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people. Because he himself suffered when he was tempted, he is able to help those who are being tempted.
Psalm 49:7-9 – No one can redeem the life of another or give to God a ransom for them—the ransom for a life is costly, no payment is ever enough— so that they should live on forever and not see decay.
Psalm 130:3 – If you, Lord, kept a record of sins, Lord, who could stand?
