Here, John shows the difference between the Spirit of Truth and that of deception. Those who confess Jesus Christ as the Messiah are from God, while those who will not out of pride & selfish ambition are not from God. This divide is very evident…either you are from God or from the world. In II Peter 2:1-3, the Apostle Peter also wrote about all the false prophets & teachers among the brethren…denying the One whom they falsely claim to serve…and all the while spinning their own interpretation of the Word from a very temporal and worldly viewpoint. Sounds a lot like today and the Progressive Church Movement, doesn’t it?
