If I am always going to sin, how do I restore my fellowship with God?

Our listener asks, “One question I have that can hopefully be addressed in our next conversation is this: If sin breaks fellowship with God, how do we know once our fellowship is restored if we are always going to sin this side of eternity? I’ve become addicted to certain sinful habits and have prayed much about it, but still have the struggle. Could this be a sign that I’ve become a reprobate, even as a saved person? My problem is this is just very painful. The pain seems to be unbearable. Things are just very heavy, and I’m looking for hope. Best regards.”
