Two errors bracket this topic: claiming all sin is the same (minimizes serious sin) and believing some sins are so minor they are barely wicked at all (hardens the conscience).

Error one: all sin is identical — this always leads to minimizing serious sin. Error two: recognizing that sins differ in severity but then concluding that certain sins (white lies, minor infractions) are cute or innocent levels of wickedness — this hardens the conscience. The biblical position holds both: all sin is genuinely wicked before God, and some sins are significantly worse than others.
