Question 11. But isn't God merciful?
Answer. God is indeed merciful but also just. Divine justice demands that sin, committed against God's supreme majesty, be punished with the supreme penalty eternal punishment of body and soul.
Question 12. According to God's righteous judgement we deserve punishment both in this world and forever after: how then can we escape this punishment and return to God's favor?
Answer. God requires that divine justice be satisfied. Therefore the claims of this justice must be paid in full, either by ourselves or by another.
