Peter builds upon his previous message, "How to Overcome Temptation," by outlining practical strategies to safeguard against sin. Using David's downfall as a cautionary tale, he emphasises the destructive consequences of hiding our sin and failing. It’s God's mercy that our sins are exposed, so that we are spared from doing further damage and further hardening our hearts. So we need to confess quickly, both to God and to a fellow believer, as encouraged in James 5:16. Peter shares practical advice on how to find the right accountability partner and to establish a lifestyle of living in the light.
