Allah may be their name for “God,” but it is not the same God that true Christians worship—that God is the ONE true living God, the Creator of everything that exists, the God of ABRAHAM, ISAAC AND JACOB. He has revealed Himself as a Triune God [Matthew 3:14-17; Matthew 28:19-20].
Anyone who goes too far and does not abide in the teaching of Christ, does not have God; the one who abides in the teaching, he has both the Father and the Son. (2 John 9)
Obviously, these so-called Christians are sons of destruction, bent on destroying the body of Christ. But they will not prevail, as God’s Word clearly states.
For whater is born of God overcomes the world; and this is the victory that has overcome the world—our faith. And who is the one who overcomes the world, but he who believes that Jesus is the Son of God? And it is the Spirit who bears witness, because the Spirit is the truth. (1 John 5:4-5,7)
