Are there sins that keep coming back? Have you accepted that God can break the bonds of those sins? Next time you are confronted with a habitual sin, or even find yourself in the midst of it, stop, and out loud rebuke it. "Jesus blood has paid the price for my freedom. His blood has severed my chains. I am a slave to this no more." And then spend a moment are two in worship. I guarantee that if you cooperate with the Spirit in this way, sin you thought you might never overcome, will lose power in your life. Your baptism accomplished something. Live in that.
