It seems like many churches shy away from talking about sin... It is a hush hush topic in the christian realm. We just like to talk about the love Jesus has for us. The mercy God gives us. The grace we exhibit with every single breath we take.
We constantly go to our Lord asking for healing and guidance, and then right after start acting like God isn't able to rescue us from our affliction.Our minds and mouths are saying "Lord, I believe you can redeem my situation," but our hearts and actions are asking "God, if you can help, will you?"
When those in our community are sinning, what is our response? Some of us condemn them. Some of us shun them. Some of us are in agony over them, while some of us really don't care. We should take our example from Moses and Aaron's reactions when prominent religious leaders and members chose to rally against the authority of God when he placed Aaron an his descendants as Israels priesthood (Exodus 28:1).
The normalization of our sins may cause us to encourage others to partake in immorality since we see no foul it. This leads us to taking God's forgiving nature for granted. Subconsciously we will believe, then we'll act, and then we'll teach that since God's grace covers all our sins we can freely act on our sinful nature.
