Nothing is so incongruous in a Christian, and foreign to his character, as to seek ease and rest; and to be engrossed with the present life is foreign to our profession and enlistment. Your Master was crucified, and do you seek ease? Your Master was pierced with nails, and do you live delicately? Do these things become a noble soldier? Wherefore Paul says, "Many walk, of whom I told you often, and now tell you even weeping, that they are the enemies of the cross of Christ." Since there were some who made a pretense of Christianity, yet lived in ease and luxury, and this is contrary to the Cross: therefore he thus spoke. For the cross belongs to a soul at its post for the fight, longing to die, seeking nothing like ease, while their conduct is of the contrary sort. So that even if they say, they areChrist's, still they are as it were enemies of the Cross. For did they love the Cross, they would strive to live the crucified life. Was not your Master hung upon the tree? Do thou otherwise imitate Him. Crucify yourself, though no one crucify you. Crucify yourself, not that you may slay yourself, God forbid, for that is a wicked thing, but as Paul said, "The world has been crucified unto me and I unto the world." (Gal. vi. 14.) If you love your Master, die His death. Learn how great is the power of the Cross; how many good things it has achieved, and does still: how it is the safety of our life.
