In a discussion with a friend about the meaning of God's omnipotence, Hebrews 6:18 came up. I have always understood this to mean that God literally cannot lie, but my friend understands it to mean that God will not lie.
so that by two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us.
No English translation quite seems to bear a "will not" interpretation, as far as I can tell. So, I am curious whether the Greek bears this. Would it be possible to render this alternately as something like "it is impossible that God would lie"?
