If you see more pictures of the minister all over the church, on signs and billboards and worldly activities being advertised, but not as much about God or His Son Jesus, and bragging about themselves first, and then talking up God later.
The question becomes 'are they promoting themselves or God?'
The Bible makes it clear that church is for promoting Jesus and his Father, not the preacher. Remember, man is NOT God and not able to save themselves let alone anyone else. That God calls ministers to serve HIM, not themselves. To direct people to God through Jesus and let God promote them - not doing it for themselves.
