A prophet of God draws people to God and not to other gods but to the father of our Lord Jesus Christ and draws people to the Word, not to himself or to some other god. And then, the things that he says come to pass. Now, that’s a little tricky because sometimes, you have a true prophet who makes mistakes (because there are some who have made mistakes). Don’t forget that you are not made a pastor, a prophet or an evangelist because you are perfect.
Does he walk in love? A key- walking in the love of Christ- is very important!
