The addiction of masturbation is more addicting then any other addiction there is. I can promise you through prayer and obedience, the Lord will heal you and take these cravings away from your mind. You have to give yourself to him and allow him to guide you in study and prayer. These thoughts and actions can be wiped away in a twinkling of an eye I promise you that. The gift of repentance is truly a gift and a miracle and works! On your computer, as your screen saver, put a picture of the Temple as a reminder that when you enter that world you have a choice the Lord or the Adversary. Trust me, at a point in my life, I never,ever thought for one moment I could tackle it. I thought to myself, will I ever be active in the church and be worthy of the sacrament and honor my priesthood. Not in a million years. The Lord invited me back and I took him up on his invitation, not only do I take the sacrament, I got to baptize my son, ordain him to the priesthood, and I am a worthy recommend temple holder. I love the temple and i’m so thankful to be able to receive it’s blessings. I never thought this could be possible as i was so caught up in sin. My life has changed forever, and yours can too.
