Psalm 103: How to Deal With Guilt Over Past Sin
Guilt over past sin is not healed by punishing yourself but by remembering what God has said about himself. Psalm 103 calls the soul to praise the God who forgives, removes transgressions, and knows we are dust.
James 2:10–11: Are All Sins Equal?
James grounds guilt not in a ranking of sins but in the one Lawgiver behind the whole law. Showing partiality is enough to make a person a transgressor, just as murder is. Yet the passage is about standing before God, not about every sin doing the same damage.
