I therefore, the prisoner of the Lord, beseech you that ye walk worthy of the vocation wherewith ye are called, With all lowliness and meekness, with longsuffering, forbearing one another in love; Endeavouring to keep the unity of the Spirit in the bond of peace. There is one body, and one Spirit, even as ye are called in one hope of your calling; One Lord, one faith, one baptism, One God and Father of all, who is above all, and through all, and in you all.
Ephesians 4:1-6
The fact that we carry the name of Jesus in our world is a wonderful privilege. It is also an awesome responsibility, and God calls us to live up to the name He gave us—to walk worthy of His calling. Jonathan Edwards wrote, “The first and the great work of a Christian is about his heart. Do not be content with seeming to do good in 'outward acts' while your heart is bad, and you are a stranger to the greater internal heart duties. See that your chief study be about your heart—that there God’s image may be planted; that there His interests be advanced; that there the world and flesh are subdued; that there the love of every sin is cast out; that there the love of holiness grows.”
The Christian who walks with a humble heart, loving others and living in the power of the Holy Spirit will bring honor to the name of Christ rather than dishonoring it. It should break our hearts to even think of bringing reproach on the precious name of Jesus. But that is what our sins do. When Nathan confronted David over his sin with Bathsheba he told him that, “by this deed thou hast given great occasion to the enemies of the LORD to blaspheme” (2 Samuel 12:14). God calls us to live holy lives as we go through this world so our behavior will accurately reflect His holy nature.
