This is a brief thought I have had recently. Obviously we repent when we have sinned. But it motivates me to look at it in two layers.
First repentance is a prayer, a conversation where I pour my heart out to God and express sorrow and ask for forgiveness.
Second, I can also look at repentance as the act of turning from sin at temptation. An act that keeps us from sinning.
To repent is to turn. So we turn after a fall but we can also turn before a fall. Both are turning.
