Personal Spirituality or Building Up of the Body of Christ?

Let's Pray:

Lord, we praise You that You have made us Your temple; we are Your dwelling place. We and You as two spirits have become one spirit. We pray that You bless us. Amen.
　
Hymn: 840
　
Freed from self and Adam's nature,
Lord, I would be built by Thee
With the saints into Thy temple,
Where Thy glory we shall see.
From peculiar traits deliver,
From my independent ways,
That a dwelling place for Thee, Lord,
We will be thru all our days,
　
Today's Verses and Footnotes: Eph. 5:22-33

Key Verse:

Eph. 4:12 For the perfecting of the saints unto the work of the ministry, unto the building up of the Body of Christ,

Eph. 4:16 Out from whom all the Body, being joined together and being knit together through every joint of the rich supply and through the operation in the measure of each one part, causes the growth of the Body unto the building up of itself in love.
　
Life Supply:

Ephesians 2:22 speaks of the building up of the church, but it gives only the principles; it does not give the details. However, the details are found in 4:16. “Out from Whom all the Body, fitted and knit together through every joint of the supply, according to the operation in measure of each one part, causes the growth of the Body unto the building up of itself in love.” By growing up into the Head, the members of the Body have something to share with one another. Furthermore, there will be the operation in the measure of each part, and the result will be the growth of the Body unto the building up of itself in love. In order to have the reality of this verse, we must be perfected by the gifts given to the Body by the Head. The saints are not perfected merely by learning doctrine. On the contrary, they are perfected through being fed. This feeding causes them to grow. For example, an infant does not need anything to be added on to his body to perfect him. As he grows, the members of his body develop and begin to function normally. A mother does not perfect her baby by teaching him to use the various parts of his body; she perfects him by feeding him. The more a child grows through receiving proper nourishment, the more the members of his body will come into their function. In the same principle, the members of the Body are perfected not by teaching, but through the feeding that causes them to grow.

Through the growth of life, we shall also arrive at a full-grown man and at the measure of the stature of the fullness of Christ. The fullness of Christ is the Body of Christ, Christ’s expression. With this Body there is a stature with a measure. When the Lord’s work in His recovery began in this country a number of years ago, we could see very little of the measure of this stature. Praise the Lord that over the years the measure of the stature has increased! This increase is the result of the perfecting of the saints through the ministry of Christ. However, as we all admit, we are still in the process of growth. The more we grow, the more we shall be able to function and to have the growth of the Body unto the building up of itself in love. This is our need today. (Life-Study of Ephesians, pp. 753-754, 758)
