Utterly reject

Lev:26 first describes about the blessings to the nation Israel if they obey and then the curses if they do not pay heed to the covenant.

Lists a huge no. of curses if Israel denies following Him and His statutes.

But at last when they realize their sin and returns back to Him, crying out, humbling themselves, the Lord says He will remember His covenant again. Not that He had forgotten and He had to be reminded, but that He is faithful and true to His own self that He would still remember the covenant even though they were unfaithful and rebelling.

Despite all the rebellion and retorting that the nation Israel had towards God, the promise and faithfulness of God is that He would not utterly reject or despise them.

The word reject means - to dismiss as inadequate, unacceptable and faulty.

A God who promised His covenant relationship with the children of Israel will not change what He has promised. His sticking on to His promise is not dependant on Israel's rebellion.

Why?

 V:44 says the reason. FOR I AM THE LORD

He remains the same, yesterday, today and forever.

2 Tim 2:13 If we are unfaithful, He remains faithful for He cannot deny Himself

If He says the wages of sin is death - then sin cannot go unpunished. That's what happened at the cross.

And if He says if we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all wickedness - He means that.

And if He says now there is no condemnation for those who are in Christ Jesus - then that's really true.

The Lord never changes.

His promise to comeback to take us back home still holds true.
