A man's sexuality is supposed to give him strength. Strength to protect, provide and to love, strength that must be harnessed and trained in Godliness, not gelded because we fear it. If we truly wish to become Godly men, of purity and strength, then we must learn to harness our sexuality, not banish it to some cage to be starved to death. We must seek to yield our sexuality fully to God and purity; this allows it to grow in the way He intended.
As a man who has fought and continues to fight for purity and Godliness in his sexuality I tell you; this is perhaps one of the hardest things you will do. The world will assault you daily with it's lusts, and the ingrained patterns of a life built in the over-sexualised western world will fight for control of your mind. Yet what I have found, as little purity as I have attained, it is so precious to me. It is this battle that has turned me from a male of God into a Man of God, and I would have it no other way.
