To bear the cross means that you refrain from doing what you have the power to do. You are qualified to fulfill your desire, yet you refrain from doing so. A person like this is the strongest person. The strongest person is not the one who is able to do something, but the one who is able not to do what he has the power to do.
Without this heart attitude it is exceedingly difficult for us to accept the circumcision of the flesh. Every affection, desire, thought, knowledge, intent, worship, and work of the flesh must go to the cross.
It is a fact that God wants to destroy every work of our flesh, but He never desires to destroy our personality. He takes no pleasure in transforming us into automata; rather He delights in having us cooperate with Him.
