Don’t believe a Gospel that doesn’t teach that you can have victory over your sin.
Jesus said, "I tell you most solemnly that anyone who chooses a life of sin is trapped in a dead-end life and is, in fact, a slave. A slave is a transient, who can't come and go at will. The Son, though, has an established position, the run of the house. So if the Son sets you free, you are free through and through” John 8:34-36 (from THE MESSAGE: The Bible in Contemporary Language © 2002 by Eugene H. Peterson. All rights reserved.)
Jesus offers a freedom that sets the captives free.
