In the disciples ask Jesus this question; what will be the sign of your coming at the end of the age? And Jesus answers and says "Be sure that no one misleads you." In other words as the last days draw to a close so will the false teachers increase and mislead people.
Here are two false prophets based on what they say as opposed to what the Scriptures say.
Both of them are well known and sell books, tapes and all sorts of material but it isn't Biblical. Beware of Paula White and Larry Huck and here is some video evidence that supports the warning!
Now read what the Bible says about Jesus being the only begotten Son of God:
¶ And the Word became flesh, and dwelt among us, and we saw His glory, glory as of the only begotten from the Father, full of grace and truth.
No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him.
¶ “For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.
“He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God.
By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him.
Folks, always check what is being preached or taught against the plumb line of God's word.
