All those that are saved from damnation is to preach and teach God's word to those that are lost. not because that person think he is better because he has been saved, but to bring as many as he can into the light so they can have eternal life the same as that person have eternal life. If Jesus would not have told us to go out into the world to preach,and teach,then his work would have been in vain. Preaching and teaching the truth is one way of destroying the works of the devil That is why we do it. according to scripture,and not vain words which is of the world. It is the love the compassion of the holy spirit that causes us to preach and teach. The word of God expose darkness and all it's activities and bring them to light for all to see.
