The Spiritual Man, CFP, 35-36, Vol. 2, Part 4 “THE SPIRIT”, Ch. 3 “Spiritual Work”
Spiritual food of a believer is nothing more nor less than accomplishing God’s work (John 4.34). The kingdom of God suffers greatly at the hands of “spiritual believers” who busy themselves with prayer and Bible study and attend only to their spiritual need. The Lord’s people should simply trust God for the sustenance of both their physical and spiritual needs. If they are willing to endure hunger in order to accomplish what God wants them to do, they shall be satisfied. Spiritual food is simply to do His will. Preoccupation with one’s own supply causes lack, whereas concern with God’s kingdom brings satisfaction. He who is occupied with the Father’s business and not with his own shall find himself perpetually full.
The child of God should not be overanxious to make new gains; what he essentially requires is to keep what he already has, for not losing is itself a gain. The way to retain what he possesses is to engage it. Burying it beneath the earth is a sure way to lose it. When a believer allows the life in his spirit to flow freely, he not only shall gain others but shall gain himself as well. One gains by losing self for others and not by hoarding for oneself. The life within a spiritual man must be released by performing spiritual labor. If one’s inner being is always open and free (it must of course be closed to the enemy), the life of God shall flow out from him to the salvation and edification of many. The moment spiritual exertion ceases, at that precise moment spiritual life is blocked. These two are inseparable.
