Barnes New Testament Notes

Verse 6. As ye have therefore received Christ Jesus the Lord. Have received him by faith as your Saviour, or as you were instructed respecting his rank, character, and work. The object here is to induce them not to swerve from the views which they had of Christ when he was made known to them. They had at first probably received their ideas of the Saviour from the apostle himself, (see the Intro.;) and, at any rate, the apostle designs to assure them that the views which they had when they "received him" were founded in truth.

So walk ye in him. Continue in those views of Christ; live in the maintenance of them; let them regulate your whole conduct. The word walk, in the Scriptures, is used to denote the manner of life; and the sense here is, that they should live and act wholly under the influence of the conceptions which they had of the Saviour when they first embraced him. The particle "so" is supplied by our translators, and rather weakens the sense. No stress should be laid on it, as is often done. The meaning is, simply, "Since you have received Christ as your Lord as he was preached to you, hold fast the doctrine which you have received, and do not permit yourselves to be turned aside by any Jewish teachers, or teachers of philosophy."

{b} "walk ye in him" 1 Jo 2:6
