For me, my spiritual baptism came 9 years after my water baptism. Meanwhile I had been possessed by various evil spirits including the antichrist, but God always had His hand on me. When my time came I was given the opportunity to pluck the fruit of choice from the tree of life and got life eternal granted in the richest form I could dream of. It's been a marvellous experience since, to see Christ manifested in various people at various times and its a thrill to witness conversions as He uses me for His instrument, especially when someone accepts Jesus in their life and they respond with joy to thank you because they were going to commit suicide this week. I've always been a bit ignorant by nature but it's so beautiful now to see miracles happening in everyday life - the pentecost is the most precious gift of Love and life manifested!
As for sin, you may be confusing addiction for sin - Christ will rebuke you if you sin, you might be confusing your definition of sin with ideas of righteous behaviour. Christ has shown me that holiness is a righteousness in the heart - not in outwardly appearance. As long as you keep your mind pure and ensure that evil thoughts are corrected immediately you will be dwelling on good thoughts and maintaining a pure temple of the mind. Remember holiness and repentance are matters of the mind, not so much the body.
Mark 7
17After he had left the crowd and entered the house, his disciples asked him about this parable. 18"Are you so dull?" he asked. "Don't you see that nothing that enters a man from the outside can make him 'unclean'? 19For it doesn't go into his heart but into his stomach, and then out of his body."
20He went on: "What comes out of a man is what makes him 'unclean.' 21For from within, out of men's hearts, come evil thoughts, sexual immorality, theft, murder, adultery, 22greed, malice, deceit, lewdness, envy, slander, arrogance and folly. 23All these evils come from inside and make a man 'unclean.' "
Every thought manifested is evidence of your heart - maintain purity in the mind and it will become apparent as others observe you. Spirituality is a matter of identifying personalities - origins of thoughts in your inner dialogue. You can learn to identify the personality of Jesus, The Father and anyone else you meet in the eternal realm, we're all friends in eternity and humanity is on the same side as God. Regardless who actually knows it or not, our fundamental goals as a people are unity, love and peace. There are people who have other goals such as greed, selfishness, dictatorship etc - these are the attributes that describe God's enemy and they are the ones you must work on through repentance as you train your mind to become Holy.
