To answer your question,If we were the Body now, why would there be so much confusion and disagreement even among those who undoubted love God? Is there sinlessness in all of those Body parts? Jesus died with a flawless record without sin to be the Head of the Body. Will His Body be flawed when it comes to Life? Are the parts of His Body to struggling against each other rather than acting always in accord with God's will?
Ephesians 4:11-14
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:
We are a body being built up, edified, converted to an edifice, if you will. But we are already this body of Christ, being In Christ. And the building up is to remove these divisions, these doctrines that blow through like waves of the sea.
And how? I think just what this says, by faith and knowledge, we all believe the same thing, all knowing the same Jesus, and where is that knowledge of a certainty found? How comes faith?
Much love!
Mark
