The sanctification set forth in the Sacred Scriptures has to do with the entire being—spirit, soul, and body. Here is the true idea of entire consecration. Paul prays that the church at Thessalonica may enjoy this great blessing. “The very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ” (1 Thessalonians 5:23).

There is in the religious world a theory of sanctification which is false in itself and dangerous in its influence. In many cases those who profess sanctification do not possess the genuine article. Their sanctification consists in talk and will worship. Those who are really seeking to perfect Christian character will never indulge the thought that they are sinless. Their lives may be irreproachable, they may be living representatives of the truth which they have accepted; but the more they discipline their minds to dwell upon the character of Christ, and the nearer they approach to His divine image, the more clearly will they discern its spotless perfection, and the more deeply will they feel their own defects.
