Let's talk about being blameless. It's not easy when you're being attacked or when you get overconfident. Then, when reality gets up in your face, and you're afraid or angry, it can cause bitterness. Whether you see it or not, God has given you a way through those places. I encourage you to make a covenant with the Lord of Lords and humble your heart before Him so His eyes may be on you.
P.S. The Lord always wins.
