“Be strong and courageous. Do not fear or be in dread of them, for it is the LORD your God who goes with you. He will not leave you or forsake you.””
Moses does not suggest courage as an option — he commands it. The strength God demands, He Himself supplies.
Israel faced real, strong nations — the fear was not irrational. Even so, God calls for courage in the face of genuine danger.
Courage doesn't come from Israel being strong, but from God going with them. The whole verse hinges on 'He goes with you.'
The double promise covers two distinct fears: being left along the way and being forgotten at the end. Neither will happen.
Moses says this knowing he will not cross the Jordan with them — the promise must outlive his absence.
Act: Name what frightens you most today and declare Deuteronomy 31:6 out loud over that situation before you act on it.
