There are (at least) three dimensions of “sin” that I see in the New Testament:
1. Sin is a CONDITION (a Power we are under that keeps us enslaved)
2. Sin is a CONTAGION (an infection that inhibits our capacity and spread easily)
3. Sin is a DECISION (a choice we have moral culpability in)
Without understanding 1 and 2, we are likely to overplay guilt and shame, preventing people from longing for freedom and healing. Without acknowledging 3, we are quick to blame environmental or situational factors for our actions and behaviors.
But when we see all three layers, we can stand in awe of the salvation that Jesus brings:
Jesus FREES us from the power of sin.
Jesus HEALS us from the infection of sin.
Jesus FORGIVES us from the guilt of sin.
