Nigerian Christians: Majority of them only preach church

Majority of Nigerian christians only preach church? Yes it's true. Haven been in their circle since my birth, that's one thing I've learnt from them. Nigerian christians have turned the bible around for their own selfish favors. Many of the pastors and men of whatever only know how to preach for people to contest to their churches. Their members have taken such attitude from them. They don't preach the true doctrine of Jesus Christ our saviour who came to redeem us from the shackle of satan. Jesus came to preach and spread love to the whole world. That's why he died for mankind. It's pitiable that most Nigerian christians only know how to preach doctrines that propagand their various places of worship. That's their main aim of preaching and objective of their preaching. This definitely has affected and is still affecting Chritiandom in general here. This has brought hatred in churches all over Nigeria. Churches in Nigeria don't cooperate but the bible said that we're one in His vineyard. The churches in Nigeria would continue to disagree until we start preach LOVE and not church. Majority of Nigerian christians only preach church? What do you think?
