God's method by which He intends to bring us all to fullness is through a body ministry operating in the Church He designed.

God has a method for bringing us to maturity in Him. His plan is that we would be transfigured by the renewing of our minds. For this process, He has given gifts of the Spirit to the members of the Body of Christ, so that there is none that has preeminence. All are necessary. His method is that every member have one or more gifts and that those gifts be the manifestation of God in the earth. Those gifts grow into ministries as they are used. They are used to minister outside the church, but they are the means by which every member ministers to every other member. It is a body ministry.

Ephesians 4:15-16 But speaking the truth in love, may grow up into him [Christ] in all things, which is the head, even Christ: From whom [Christ] the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love.

No person will come to the measure of the stature of the fullness of Christ.  The Church will come to that stature.  It will be Christ's body.  It already is Christ's body, but has not walked into the fullness of the experience.
