Fourthly: If God is to be all in all, sacrifice everything for His kingdom and glory. "That God may be all in all." This is such a noble, glorious, holy aim that Christ said, "For this I will give my life. For this I will give my all, even to the death of the cross. For this I will give myself." If it was worth that to Christ, is it worth less to you? If one had asked Jesus of Nazareth, "What is it Thou hast a body for; what is to Thee the highest use of the body?" He would have said, "The use and the glory of my body is that I can give it a sacrifice to God. That is every thing." What is the use of having a mind; and what is the use of having money; and what is the use of having children? That I can give them to God; for God must be all in all in everything. I pray God that He may give us such a sight of His kingdom, and His glory, that everything else may disappear. Then, if you had ten thousand lives, you would say, "This is the beauty and the worth of life, 'that God may be all in all' to me, and that I may prove to men that God is more than everything, that life is only worth living as it is given to God to fill." Do let us sacrifice everything for His kingdom and glory. Begin to live day by day with the prayer, "My God, I am given up to Thee. Be Thou my all in all." You say, "Am I able to realize that?" Yes, in this way: Let the Holy Spirit dwell in you; let the Holy Spirit burn in you as a fire, and burn in you with unutterable groanings, crying unto God, Himself to reveal His presence and His will in you. In the eighth of Romans, Paul spoke about the groanings of the whole creation. And what is the whole creation groaning for? For the redemption, the glorious liberty of the children of God. And I am persuaded that was what Paul meant when he spoke of the groanings of the Holy Spirit--the unutterable groanings for the coming time of glory when God should be all in all. Christians, sacrifice your time; sacrifice your interests; sacrifice your heart's best powers in praying, and desiring, and crying that "God may be all in all."
