V.11-13 Moses appoints two groups to stand on these separate mountains which were just inside the promised land. On Gerizim, to bless the people (for obeying) — on Ebal, to pronounce the curses if they disobeyed the law. Can you find the blessings? Not one word.
To summarize our whole chapter: vvs. 1-10 present to us the heart of a gracious God, and the thoughts of God toward His beloved people. Yet vvs. 11-26 show us the actual condition of these people — they were on the ground of law — their blessings would depend on their obedience! So the sad result of Israel’s real state before God. BUT because of God’s grace and love, He has sent a Savior, Who has taken the curse for us and brought us into the position of total blessing. (Read Rom. 6:1515What then? shall we sin, because we are not under the law, but under grace? God forbid. (Romans 6:15)).
