1 John 4: 1-6
Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world. 2 By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God; 3 and every spirit that does not confess Jesus is not from God; this is the spirit of the antichrist, of which you have heard that it is coming, and now it is already in the world. 4 You are from God, little children, and have overcome them; because greater is He who is in you than he who is in the world. 5 They are from the world; therefore they speak as from the world, and the world listens to them. 6 We are from God; he who knows God listens to us; he who is not from God does not listen to us. By this we know the spirit of truth and the spirit of error.
Here is the conundrum of our day: How does one respond when people profess Jesus Christ and manifest behavior which appears in conflict with the spirit of the teachings of Christ?
