Most TV / Randi preachers (large majority) are bad.
here are some that are not.
David Jeremiah
Chuck Swindoll
Billy Graham (now deceased)
John Macarthur
Charles Stanely, Sr. is legit, imo.
Another great evangelist, long deceased, was Charles Fuller, whose medium was radio. His Old Fashioned Revival Hour broadcasts can still be heard at the Old Fashioned Revival Hour's website.
Add Andrew Wommack to the good teacher list. The best.
you forgot a couple of important solid Christian teachers/preachers
Dr Charles Stanley
Adrian Rogers (now deceased- very solid
Christian teacher)
There are a great many m ore truly solid Christian preachers who love the Lord- and don’t beg for offerings, and claim they need multi million dollar personal jets to fly everywhere constantly-
1. Jeremiah has endorsed the prosperity teachers and has lost my confidence, and this after years of liking what I heard from him.
2. Swindoll uses versions of what I call "un-Holy Bibles" in that he uses and endorses versions like "The Message" and The Living Bible. I can't listen to anyone who doesn't preach from, or ridicules, the Authorized Version, the King James.
3. Billy Graham was a sell-out to missionary churches world-wide. He did more to hurt the Gospel than he ever did to help it.
Alistair Begg
Ravi Zacharias
Tony Evans —Oak Cliff Bible Fellowship (focus is on restoring the black family)
And some of those don’t have the truth of Christ.
Discipleship Tape Ministries, Russell Kelfer (now deceased) have good sermons that he preached before his death.
Ravi Zacharias (not really a preacher)
Erwin Lutzer
J Vernon McGee (deceased)
Adrian Rogers (deceased) was one of the best preachers. His preaching can be found on YouTube.
