Does your preacher tell you the truth and quote the Word? Or does he try to win you over with flattery?

Jude 1:16
16 These are grumblers, complainers, walking according to their own lusts; and they mouth great swelling words, flattering people to gain advantage.
(NKJ)

Rom 16:18
18 For those who are such do not serve our Lord Jesus Christ, but their own belly, and by smooth words and flattering speech deceive the hearts of the simple.
(NKJ)

1Thes 2:5
5 For neither at any time did we use flattering words, as you know, nor a cloak for covetousness-- God is witness.
(NKJ)
