Despite its smallness and visible weaknesses, as the complement of Christ, the church is also in an exalted position. We members do not literally add a thing to Christ's divinity, but in His view, He is not complete and will not be complete until united with His bride. Thus, as He sanctifies and shapes us in holiness, He gradually fills His bride's every part with every gift needed to enable her to function effectively so that she, as a whole, can glorify God in her overall responsibility to our Father and to our Lord and Savior. Since everything in Christ's spiritual body comes from Him, He is everything to every member within it.
No religion but Christianity offers such an exalted and loving, spiritual Being sent to labor on behalf of its adherents. He is our Creator, our Lawgiver, the Forgiver of our sins, the Dispenser of His Spirit, the Giver of eternal life, our Guide through life who blazes the trail before us, and the Enabler of true spiritual growth and overcoming.
This body of believers is not contained within one corporate entity, and an individual cannot just go out and join it. The Father must lead a person to it (John 6:44). When He does, the newly called person will find people who are keeping God's commandments—all ten of them—in both letter and spirit. They will worship God in spirit and truth (John 4:24) without dodging spiritual realities, and they will sacrifice themselves despite personal costs. They will be honest to a fault, trustworthy, and uncomplaining. They are not driven by envy and covetousness, nor are they fixed on immediate or self-gratification.
The Kingdom of God is the vision that drives them. They strive to transform into the image of Jesus Christ and to glorify the Father and Son in everything. They live solidly in the present, aware of many of its harsh realities, but they make every move with their gaze on their eternal future. They truly are pilgrims, people who humbly see themselves as mere tiny specks in a vast and awesome purpose yet privileged beyond all bounds. They believe that purpose, and in gratitude, give themselves by faith to see it accomplished in their lives.

Where Is God's True Church Today?
The subject of this paragraph begins with the Father and shifts to the Son. At the end, however, the church—its relationship to Christ and among the members—becomes the focus. The major theme of the book of Ephesians is unity. It tells us why we are able to have it and what we must do to maintain it.
Paul describes the church as "a body." This is essential to unity and to preaching the gospel, keeping us from not losing our focus. We have to have God's perspective of what we are. We are a body, meaning a living organism, or by analogy, the human body.
Any organism, like the human body, is unified. Each part cooperating for the good of the whole. Notice that Paul does not use a word like "team." The word "team" has some of the same associations as "body," but it is not as accurate. With "body," Paul not only gets across the concept of association within an organism to accomplish a common work, but it also the sense of a far closer relationship and more critical responsibility, in which each part responds to the will of the head.
We are so close to Jesus Christ that Paul describes us as "His fullness," that is, we fill Him out. We complete Him. Paul does this to relate both the closeness of our association with Christ and our responsibility to Him to do everything in our power to build the strength of both.
The church—we—are Jesus Christ's complement. This is the highest honor a human being can be given! There is nothing greater than to say that we are a part—we fill out, we complete—the body of Jesus Christ! It is as though Jesus Christ our Creator considers Himself incomplete until we become part of Him. He is a Bridegroom, incomplete without His Bride. As a vine, He is incomplete without the branches. As a Shepherd, He is incomplete without His sheep. And so also is He incomplete as a Head without a body, without members, through whom He works and is glorified as they cooperate and yield to Him.
