1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.The Bible says the testimony that I received was of God, I'll believe the Bible, thanks for your interpretation though.
2 Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God:
3 And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
Delphi, just because someone says it is “Jesus” doesn’t mean it is the same Jesus. There is a guy in Central America claiming to be Jesus come in the flesh as well. His claims do not match Scripture’s claims. Neither do Mormonism’s.
John is speaking of Christ as the living Word that became Flesh (1Jn.1)
And the Living Word that is one with the Father and the Holy Spirit (1Jn.5:7).
So, while John is addressing a particular heresy in 1Jn.4 regarding gnostics who deny that Christ came in the flesh, he also makes it very clear that Christ is the Word, the Second person of the Tri-unity of the three, which became flesh (Jn.1:1-2,see also what Paul wrote- 1Tim.3:16) and if you deny that (which Mormons do) you are denying the record the Father gave regarding His Son (1Jn.5:7-10).
So, it is you who needs to do some serious praying, and not over the Book of Mormon, but over the Bible, and not just the portions that you want.
