As for you, let that stay in you which you heard from the beginning. If what you heard from the beginning stays in you, you also shall stay in the Son and in the Father.
Everyone who believes that יהושע is the Messiah has been born of Elohim, and everyone who loves the One bringing forth also loves the one having been born of Him.
Because many who are leading astray went out into the world who do not confess יהושע Messiah as coming in the flesh. This one is he who is leading astray and the anti-messiah.
