For Christ’s fundamental concern was with the soul rather than with the body, with the next life rather than with this one.  That becomes clear when we ask the question, “Why did he wait in Gethsemane to be arrested and crucified?  Why did he not escape and continue his ministry of healing people’s minds and bodies of disease?”  

The answer is that he came to heal people of moral and spiritual evil, of the infection of sin, and that is something infinitely more serious than any physical need, because its destructiveness extends beyond the grave into all eternity.  That was his true mission and he would not run away from it by running away from its inevitable cost, the Crucifixion.
