Because most are what I call “get rich quick and be happy” churches. They are in it for the money. Osteen being the most successful.
Personally, I don’t believe they believe in God. I KNOW many of the preachers do not know Jesus IS God in the flesh.
I believe what my mom believed. You must be “called” to preach. Otherwise, you are a fraud.
Matthew 28:18-20
18 Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. 19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you.
