The ESV has here, You have been filled in him.
Back to Ephesians, chapter 4 this time, we will see a similar phrasing that shows that it is more that He fills us rather than we fill Him.
So in this way it shows that we do not have the fullness of Christ. We start pretty much at empty and we need to be filled with the fullness of Christ until we get to the point where we are of His measure and stature.
So we start out where we need to get rid of a lot of our humanity and begin backfilling with the new man. And those things that we are putting on reflect true righteousness and holiness.
