Matthew 24:3-5
And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world? And Jesus answered and said unto them, Take heed that no man deceive you. For many shall come in my name, saying, I am Christ; and shall deceive many.
We have to be careful and not follow the teachings of a well spoken man. There are people out there who say they are working for Christ but are only going where the Devil leads them. Just because a message sound nice and the person teaching is nice does not mean it is from the Lord. We have to take everything and compare it to the words of God and all of his teachings. It will be confusing at times, but the Holy Spirit will be there to help.
