Who is the True God and True Name

For "everyone who calls on the name of the Lord shall be saved." But how can they call on him in whom they have not believed? And how shall they believe in him of whom they have not heard? And how shall they hear without a preacher? And how can they preach unless they are sent? Thus it is written, "How beautiful are the feet of those who bring good news! So I warn anyone who is speaking by the Spirit of God can curse Jesus; no one can say "Jesus is Lord" except by the Spirit Santo.En this can discern who has the Spirit of God: every spirit that acknowledges that Jesus Christ has come in the flesh is of God: every spirit that does not acknowledge Jesus is not of God but of antichrist. You have heard that it cometh; in effect, is now in the world.
