Q12: According to God's righteous judgment we deserve punishment both in this world and forever after: How then can we escape punishment and return to God's favor?
A12: God requires that His justice be satisfied. Therefore the claims of His justice must be paid in full, either by ourselves or another.
Q13: Can we pay this debt ourselves?
A13: Certainly not. Actually, we increase our guilt every day.
Q14: Can another creature--any at all--pay this debt for us?
A14: No. To begin with, God will not punish another creature for what a human is guilty of. Besides, no mere creature can bear the weight of God's eternal anger against sin and release others from it.
Q15: What kind of Mediator and Deliverer should we look for then?
A15: One who is truly human and truly righteous, yet more powerful than all creatures, that is, one who is also true God.
