11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:13 Till we all come 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:14 That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;15 But speaking the truth in love, may grow up into him in all things, which is the head, even Christ: (Ephesians 4)
We are meant to use the sources of nourishment that God has given us to come to a “unity of the faith” and “the knowledge of the Son of God,” eventually attaining “the measure of the stature of the fullness of Christ”—all things that are either disbelieved or nearly impossible to find in this world at the moment.
How can we be surprised when we are, indeed, “...tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive?”
What does it mean to “grow up into him in all things?” Is that even possible? The world would tell you that it is not.
It is possible, but it should come as no surprise that it will take sincere repentance—a sincere recognition of your woefully underdeveloped state and a complete trust in God’s ability to lift you out of it. It should come as no surprise that what he teaches you will be as completely foreign to you as air is to a newborn and that your continued ability to partake of the “breath of life” will require a permanent change to your heart. It should come as no surprise that your growth relies on the elimination of that which does not serve you well (even if it served you before) and the assimilation of anything that does. It should come as no surprise that the increase of joy that comes with that growth is dependent upon your putting off the natural man and becoming a saint.
And it should come as no surprise that any heavenly society will not be established until individuals start working towards and attaining their full Christ-like potential.
