We are to wait upon our Master humbly, reverently, feeling it an honor to do anything for Him. We are to be self-surrendered, given up always to the Lord—free men—and yet most truly serfs of this Great Emperor. We are never so truly free as when we admit our sacred serfdom….Often Paul calls himself the servant of the Lord and even the slave of Christ. And he glories in the branding iron’s marks upon his flesh. “I bear,” says he, “in my body the marks of the Lord Jesus; therefore let no man trouble me.” We count it liberty to bear the bonds of Christ! We reckon this to be the most supreme freedom, for we sing with the Psalmist, “I am Your servant; I am Your servant. You have loosed my bonds.” — Charles Haddon Spurgeon
