Sickness is but another name for sin. Healing is but another name for God. The miracle is thus a call to Him.
W-356.1. Father, You promised You would never fail to answer any call Your Son might make to You. 2 It does not matter where he is, what seems to be his problem, nor what he believes he has become. 3 He is Your Son, and You will answer him. 4 The miracle reflects Your Love, and thus it answers him. 5 Your Name replaces every thought of sin, and who is sinless cannot suffer pain. 6 Your Name gives answer to Your Son, because to call Your Name is but to call his own.
