You are a Christian now: you can’t be complacent. This good news which you have received, you must tell someone about it (Mark 16: 20); spread the word from where you are to where GOD would lead you to.
While I’m not sure the flesh would hardly resist satisfying itself, I'm pretty certain the spirit is often ignored and the soul, tormented, in those moments of sins – secret and sedating. You can say this is a declaration of the internal war. For sin to happen, there is war among your members.
