I'm not saying it's what He can and can't do - I'm saying its simply not important, nor is it worthy or profitable towards salvation and the continuing mortification of sin.
*I* cut myself off from nothing - I take what He gives freely, which is His grace, mercy and love - I care about nothing else that is earthly.
Those who came to Jesus seeking healing weren't turned away by the likes of your thinking, I can assure you that. Jesus is the same yesterday, today, and forever. He blesses me with material things too, I just don't worship them as I worship Him :)
