You have to fast for years, go to church for years, do everything for years! If it's not from the heart, if you don't feel something towards that God, towards Jesus Christ, it's all in vain! Now, for example, if I first consider myself the greatest sinner because I've done all sorts of things in life, because I didn't respect even ten commandments of God. There was no one to teach me, there was another system where they say there's no God, there is God.
