The greatest sin is the sin against the Holy Spirit because it is unforgivable_Matt 12:31. Do not condemn a "man of God" for judgement is of God himself. If you do,it is a sin against the Holy Spirit. Same way Jesus was accused of casting out demons by the power of prince of demons(Beelzebul) by the Pharisees_ Matt 10:34. Please brethren be mindful of what you say. Mind you, demon cannot cast out demon! Kingdom divided against itself cannot stand_Matt 12:25. If satan cast out satan it is divided against itself_Matt 12:26.
