How can I overcome sin?
Sin that has become a habit can feel like an impossible mountain to climb. But here’s what you need to remember—when you were born again, you instantly became an overcomer (1 John 5). You are an overcomer. That’s who you are. That’s what you are.
The devil would give anything he’s got to keep you from finding that out. Jesus already overcame him for you and gave you the authority to knock him down anywhere, anytime. All you have to do is pull the sword of the Spirit on him.
