The book of 2nd John gives us a glimpse of who Jesus is in the  New Testament (N.T).

The book of 2nd John is the shortest of the four single chapter books in the New Testament with only 13 verses, but in these 13 verses are 3 primary or direct references to Jesus

2nd John 1:3 declares Jesus as The Lord and The Son of the Father and 2nd John 1:9 establishes that Jesus is The doctrine of God. 

Jesus Christ is the doctrine of God, not a cooked up fable, dogma or tradition of man or man’s own interpretations. In fact, this book, in its core is a warning to take heed against such false teachings and counsels us to walk in truth and in love (obey his commandments) lest we fall.

The author in fact commends a lady as the elect lady. She is not identified to us. But the author knows her.
We as the church are the elect lady, the bride of Christ. We are not identified by the world, but the author and finisher of our faith, Jesus Christ, knows us.
The Church must acknowledge that Jesus is the Lord, the Son of the Father and that He is the doctrine of God.

In 2nd John, Jesus Christ is Lord, the Son of the Father and He is the doctrine of truth and love by whom we must Walk, lest we fall.

Points to ponder:
Are you and I walking in truth and in love (obeying his commandments)?
