With pornography, is it online or magazines? If it is a magazine, you need to cancel your subscription and throw out all materials. If it online, it would be better to take a sledgehammer to your computer than go to hell over this.
Several things here. God is watching you. There are no secrets, and everything that is private will later be public information. Everyone will know every thought and deed we ever had.
With pornography, realize these are human beings, not sex objects. They are somebody’s girlfriends, wives, and daughters. By buying, or participating in, pornography, you are not only placing your own soul in jeopardy but helping perpetuate this immoral but very lucrative business get more victims and spread.
With both masturbation and pornography, I think people feel it is fulfilling some unresolved need. It is turning to these other means, instead of to real relationships. God made us in his image with the gift of sexuality. We must cherish and not misuse it.
Oh yes, and pornography often does hurt relationships, marriages especially. It’s really a form of infidelity. In marriages, it makes the wife put an impossible competition with these perfect, young models.
