"Now it shall come to pass, if you diligently obey the voice of the LORD your God, to observe carefully all His commandments which I command you today, that the LORD your God will set you high above all nations of the earth. And all these blessings shall come upon you and overtake you, because you obey the voice of the LORD your God..."

"But it shall come to pass, if you do not obey the voice of the LORD your God, to observe carefully all His commandments and His statutes which I command you today, that all these curses will come upon you and overtake you..."

—Deuteronomy 28:1-2, 15

God promised great blessing on Israel for obedience.  The promised blessings continue for 12 verses, from verse 3 through verse 14.

God also warned Israel of horrendous curses for disobedience.  The list of curses continues for 53 verses from verse 16 through verse 68.

What might we take away from this?

God wants to bless his people, but obedience is required.

God is most serious about disobedience. issuing the warnings in an extended and graphic manner.

We are not ancient Israel, so the particular blessings regarding Israel and the Promised Land do not apply; but the principles of blessing for obedience and curses for disobedience certainly do apply.

None of us has, nor ever has, is, or will obey perfectly.  This means we have no hope of God’s blessings and only the terror of His curses.

BUT!  On the cross, our sins were laid on Jesus, and He experienced all the curses we deserve, even though He is sinless.  And because of that, those who trust in Jesus receive all the blessings only Jesus deserves, even though we are sinful.

How great is our Savior?! 
How great is God’s grace?!
