Deut. 28 - IF you will diligently obey the Lord your God, being careful to do all His commandments which I will command you... all these blessings will come upon you and overtake you.
v 9 The Lord will establish you as a holy people to Himself, as He swore to you.
IF you will not obey the Lord your God, to observe to do all His commandments and His statutes...then all these curses shall come upon you and overtake you.
I once heard it said the Israelites were not a chosen people because they were special but are special because they were chosen. They are God’s own possession and so are we who have trusted in the saving work of Christ.
While I see much chastening outlined in the latter 2/3rds of this chapter, I do not see God relinquishing His ownership of them. I think we may be assured also that while God does chasten those whom He loves; it is with a view towards turning our hearts to acknowledge His sovereignty over our lives. We were bought dearly at great cost and should heed the warning given here but in another sense, I take comfort from the inexorable quality of God that he will “come upon us and overtake us” as outlined in both the blessings and the curses.
