|And we know that the Son of God has come, and has given us understanding so that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life. |
|1 John 5:20|
The coming of the Lord Jesus revealed to us Him who is true, that is, the true God. God the Father can only be known through the Lord Jesus Christ. Jesus said, "No one comes to the Father except through Me." John is teaching what the Gnostics denied, namely, that Jesus Christ is God, and that eternal life is found only in Him.
