God is the real judge, even those imitations doctors of law and proffessor in the court are nothing but ants to God. Who am I, to say to my brother or sister s/he won't enter the kingdom because s/he is a sinner. What if s/he repent a minute before s/he dies and I fell down and sin in the same hour. So God is the greatest judge. We should pray for our brothers and sisters who sin secretively and God is going to help them in their troubles. We are all His flock, but this doesn't mean we must sin purposely and tell others not to judge you. Do you remember what happen to the Israelites in the mountain of Jerico.
