Eph 4:13 Till we all come ( attain/arrive) in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:
So much with Christ Jesus is ascending, arising or stepping into what He is currently.
This can be called arriving at and attaining to.
As He is, so are we who have Him.
Call it stepping up and into the same level of energy, power and glory that He lives in.
It’s in the renewal of the mind.
Call it putting on the perfect man whom Christ is in the stature of the measure of His fullness.
The old atomic model contained a nucleus with electrons in different energy levels revolving around it.
One has to ascend into the same energy level of life that Christ Jesus dwells in heavenly places.
Its as jumping electron energy levels.
