Self-Gratification? Don't Sell Times of Intimacy With God at Such a Cheap Price

This topic is really sensitive, and what I'm about to say might make some of you uncomfortable. Someone wrote in, "I want to talk about a significant struggle—a place of battle, struggle, falls, and failures. About 3 to 4 years ago, God saved me, and since then, I've changed in many ways. However, one particular sin has barely changed: the sin of masturbation. I've been heavily addicted since I was 12, and now, at 23, I've had some small victories but keep falling back. Honestly, I still feel like a slave to that sin. Does this mean that the Son has not set me free yet? Or even worse, that I'm not saved?"
