Let's face it all humans have feet of clay. Just when you like a preacher somebody will call him a false prophet. Why is that ? We are imperfect people being judged by imperfect people. We are all sinners and we fall short of the glory of God.
But i believe we like preachers who preach what we like. Let me suggest a simple guide. Look for preachers who preach the truth with love. Look for preachers who will laugh and cry with you. Look for preachers who truly love Jesus Christ. Look for preachers who admit that they are humans like you. Look for preachers who will help you grow as a Christian.
By the way, maybe you have a better list, please share it with me or us.
