6 Therefore as you have received Christ Jesus the Lord, walk in [union with] Him [reflecting His character in the things you do and say—living lives that lead others away from sin], 7 having been deeply rooted [in Him] and now being continually built up in Him and [becoming increasingly more] established in your faith, just as you were taught, and overflowing in it with gratitude.
Walk in union with Him.
Means live your life aware of Him and in agreement with Him.
So that you will reflect His character in the things you do
and say, which will lead others away from sin.
Be deeply rooted in Him,
Continually built up in Him
Becoming increasingly established in your faith
Just as you were taught
And overflow in it with gratitude.
