1 John 5:20 AMPC

[20] And we [have seen and] know [positively] that the Son of God has [actually] come to this world and has given us understanding and insight [progressively] to perceive (recognize) and come to know better and more clearly Him Who is true; and we are in Him Who is true-in His Son Jesus Christ (the Messiah). This [Man] is the true God and Life eternal.
