“And not holding fast to the Head, from whom all the body, nourished and knit together by joints and ligaments, grows with the increase that is from God.”
“grows with the increase that is from God”
“Grows” — the whole body grows as God wants it to grow. The growth of the “body” here is the church rather than the physical body.
“Increase” means to increase in the extent of or in the instances of an activity or state — to increase, to grow, to spread, to extend.
“In whom the whole building is held together and extends into [or ‘increases until it becomes’] a sacred temple in the Lord” (Eph 2.21).
“From God” — God is the source of grace. True spirituality comes from life, the life of God, not from laws of Gnosticism. It is the nature of new life in Christ to grow. There is no growth apart from truth.
Spiritual paralysis comes from disconnection from the head.
Muscular action is caused by stimulation of nerve cells from the brain and spinal cord. When the nervous system is not working properly, it affects the muscles. Spiritual disorder is caused by distorted link to Christ the head. If we do not draw strength from him, spiritual disorder will follow. Sin paralyzes the spiritual life.
