It's amazing when speaking to many people, how few know this. 2Cor11v4 "For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted-you may well put up with it". NKJV.
I would like to couple these verses too, Rom16v17-18 "Now I urge you, brethren, note those who cause divisions and offenses, contrary to the doctrine which you learned, and avoid them. 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.
The word contrary in Greek is para, being parallel & close to the true doctrine, gospel, Spirit & the real Jesus, that to most they would find comfort with. To be a true follower of Christ, you have to separate from those who look immaculate & smooth, & proclaim a prosperity gospel, where if you give them your money, you will get back a hundredfold. They have massive churches, because it tickles the ears of the hearers & makes them feel good. The real Jesus says we have to crucify self daily, & live by His Spirit, & thus be hated by the world, who are full of themselves. Lk9v23.
