Excerpt from: "A Present Salvation."
So it is that “every spirit that confesses that Jesus Christ has come in the flesh is of God, and every spirit that does not confess that Jesus Christ has come in the flesh is not of God” (1 John 4:2, 3). Note again the present tense. It is not enough to confess that Jesus Christ did come in the flesh; that will bring no salvation to anybody. We must confess, from positive knowledge that Jesus is just now come in the flesh, and then we are of God.
