How does God use man? Well, the mission is to tell others that a Revelation of Jesus Christ exists, Gal. 1:10-12. Those that have had a revelation will speak it. The mission of preachers and teachers that have had a revelation of Jesus Christ is to tell others they are not complete (soulishly) until they have had a revelation of Christ as their only life, Gal. 2:20. God reveals Christ in you to you in His time, Gal. 4:1-2. I cannot give the revelation, I cannot bring the revelation, but I can and must tell believers, we can search the scriptures to see Christ as their only life. We know religion cannot preach anything they don't possess, and will in time hinder your spiritual growth.
