Where we have failed is in the practical application of the teaching concerning the crucified life. Too many have been content to be armchair Christians, satisfied with the theology of the cross. Plainly Christ never intended that we should rest in a mere theory of self-denial. His teaching identified His disciples with Himself so intimately that they would have had to be extremely dull not to have understood that they were expected to experience very much the same pain and loss as He Himself did.
The healthy soul is the victorious soul and victory never comes while self is permitted to remain unjudged and uncrucified. While we boast or belittle we may be perfectly sure that the cross has not yet done its work within us. Faith and obedience will bring the cross into the life and cure both habits.
