““I sanctify myself, that they themselves also may be sanctified in truth.’ The giving up of His will to God’s will in the agony of Gethsemane, and then the doing of that will in the obedience unto death, this was Christ’s sanctifying Himself and us too. [. . .] Let us understand and hold it fast: Christ’s giving up His will in Gethsemane and accepting God’s will in dying; Christ’s doing that will in the obedience to the death of the cross, this is His sanctifying Himself, and this is our being sanctified in truth. ‘In the which will we have been sanctified.’ The death to self, the utter and most absolute giving up of our own life, with its will and its power and its aims, to the cross, and into the crucifixion of Christ, the daily bearing the cross—not a cross on which we are yet to be crucified, but the cross of the crucified Christ in its power to kill and make dead—this is the secret of the life of holiness—this is true sanctification. [. . .] The steps in this path are these: First, the deliberate decision that self shall be given up to the death; then, the surrender to Christ crucified to make us partakers of His crucifixion; then, ‘knowing that our old man is crucified,’ the faith that says, ‘I am crucified with Christ;’ and then, the power to live as a crucified one, to glory in the cross of Christ.””
