1 Corinthians 3:23

and ye are Christ's, and Christ is God's.

This being true, that the world's wisdom is foolishness before God, let therefore no one glory in men. Both the self-praise of the world's wise men and the foolish adoration given to them is here condemned; and this all the more so, since everything is to serve the Christians in the Church, in their faith. So closely is the Church, so intimately are all believers, connected with Christ that they partake of His wonderful glory, Ephesians 1:19. They are no longer in any way dependent upon men, upon the wisdom of this world, but have a direct claim upon the service of everything which belongs to God and Christ. At the service of the believers, by the grace of God, stand Paul and Apollos and Cephas, all the apostles and ministers whom He has sent to proclaim the glorious truths of salvation. At their service stands the world itself, the whole world with all its forces and resources; the right use of them all is in furthering the cause of Christ. In the service of the believers stand both life and death; whether they live, they live to the Lord, and whether they die, they die to the Lord, Romans 14:8. In their service stand both things present and things to come; all states, conditions, offices, trades, professions, everything should aid in the spread of the Gospel, of the Christian faith. "Everything in the wide world belongs to Christ the Ruler. What emperors, kings, princes, government, and subjects have and possess, that is all Christ's. It has all been subjected to Him. All men must be under this King and Ruler, either in grace or in disgrace. Christ has everything in His hand and power. " And so Paul concludes in a burst of confident triumph: But you are Christ's, but Christ is God's. Since the believers belong to Christ by faith, in and through Him their royal power is exercised. In this relation, therefore, there is praise for no one but Christ. And Christ is God's, the believers thus, through the Son, being united also with the Father and partaking of His eternal power. God, therefore, is all in all, and it behooves all Christians, instead of spending valuable time in petty bickerings, in forming factions, and in boasting in men, to devote the energy of faith to the spread of His honor and glory. God's field of tillage, God's building, God's temple, we Christians are, because we belong to Christ. And this great honor, on whose account we fall down before God in humble adoration, teaches us to deny the ungodliness of the praise of men and to glory in the Lord alone.

Summary. The apostle reproves the Corinthians for their carnal behavior in forming factions, shows the equality of all ministers, points to Christ as the only Foundation of the Church, predicts that the fiery test of the last day will burn away everything but the substance of the works done in the Church, and warns against the desecrating of the temple of God.
