Define "his will"
because how one defines a person as doing Gods will, will define how one should respond..
That is the $64,000 question...because it is the will of God that we obey authorities...so if anyone was speeding his car and going over the speed limit...he would not be doing the will of God....in this theology....he would not go to heaven if he crashed his car and died...
There are a few things like this that are the "known will of God"...like pray without ceasing....rejoicing always....in everything give thanks....what happens if we are sad for a few days and then die of a heart attack...do we still go to hell and not heaven because of our failure to "do the will of God?"
There must be something else to this "doing the will of God"...of course grace believers know the truth of "doing the will of God"..He's called Jesus our righteousness.....and we walk out who we are in Him now...because we believe in Him and what He has done in His finished work for us.
We are called believers for a reason.....
