1 Thess 2:4, Gal 6:12-14, Jn 5:44
We must preach the true gospel that Jesus is the Christ. We must not preach gospels to please people. (Gal 1:10, 1 Thess 2:4)
Gal 1:10 For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ.
1 Thess 2:4 But as we were allowed of God to be put in trust with the gospel, even so we speak; not as pleasing men, but God, which trieth our hearts.
If we seek the glory of man, we cannot believe that Jesus is the Christ. (Jn 5:44)
Jn 5:44 How can ye believe, which receive honour one of another, and seek not the honour that cometh from God only?
