From; Ellen G. White
"COOPERATION".

“Take ye away the stone.” Christ could have commanded the stone to remove, and it would have obeyed His voice. He could have bidden the angels who were close by His side to do this. At His bidding, invisible hands would have removed the stone. But it was to be taken away by human hands. Thus Christ would show that humanity is to co-operate with divinity. What human power can do divine power is not summoned to do. God does not dispense with man’s aid. He strengthens him, co-operating with him as he uses the powers and capabilities given him. – {DA 535.3}
