Psalm 111:9-10
“He has sent redemption to His people; He has commanded His covenant forever: Holy and awesome is His name. The fear of the LORD is the beginning of wisdom; A good understanding have all those who do His commandments. His praise endures forever.”
Forever does not always mean “without end” in biblical usage, but it appears, in Psalm 111:9-10, that does mean “without end”. Sometimes, forever means “as long as conditions exist”, but in Psalm 111:9-10, the subject is a covenant, commandments, and righteousness that endure forever (reference verses 3, 5-10). In six out of ten verses, various words indicate “time without end” and reinforce “forever and ever.”
The covenant talked about is the New Covenant, the one that will endure forever, as opposed to the Old Covenant. In Hebrews 8, the Old Covenant is declared to be obsolete. The important point is that God’s commandments are connected to the covenant that will last forever. The commandments are definitely not done away with the coming of the New Covenant. In Psalm 111, God indicates that His commandments are not done away with the coming of a covenant that will last forever.
However, in Protestantism theology, since the Old Covenant is done away with, then God’s law is also done away. So, Protestant theologians decisively deal with the Old Covenant and the law of God in one fell swoop. However, what they propose is not correct. It does neatly get God’s law out of the way, revealing an attitude behind their theology.
Their teaching continues by stating that a reason God’s Law had to be done away is that it is too difficult to keep, as well as harsh and enslaving to the Christian. Human nature is certainly agreeable to this conclusion, because it is ever willing to shift the blame elsewhere to justify human conduct.
