Beloved, do not believe every spirit, but test the spirits to see whether they are from God; for many false prophets have gone out into the world. By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, and every spirit that does not confess Jesus is not from God. And this is the spirit of the antichrist, of which you have heard that it is coming; and now it is already in the world. Little children, you are from God, and have conquered them; for the one who is in you is greater than the one who is in the world. They are from the world; therefore what they say is from the world, and the world listens to them. We are from God. Whoever knows God listens to us, and whoever is not from God does not listen to us. From this we know the spirit of truth and the spirit of error. (1 John 4:1-6, NRSV)
Fake News is rampant. But here is the real issue. There is no such thing as fake news. There is false news and incorrect news. But to say news is fake is like calling a human being illegal.
You can not believe everything you hear or read. And as followers of Christ, we should discern any information we get regardless of the source to make sure it is the truth that will help us be better followers of Jesus.
All news is not true and will not edify the body of Christ, so discern everything you hear and test if it is from God.
Test the things you hear and read so that you might continue to grow as a disciple of Jesus.
