Verse 20.— But ye, beloved, building up. The apostle now turns to the brethren in earnest exhor­tation: You are built upon the foundation of Jesus Christ; you are a part of his spiritual edifice, the temple he erected in the world. The faith you have is a most holy faith; you believe Jesus Christ to be God's Son; you take him for your Prophet, Priest and King; you acknowledge him to be your Savior, your guide. Now, you can build yourselves anew, day by day, by keeping up your connections and relations with your living head, by your prayers in the Spirit. This is not only your duty, but the blessed privilege of disciples of Christ who are God's children.
