Skeptics ask whether the Law given by Yahweh was perfect (Psalm 19:7) or if it was flawed and needed replacement (Hebrews 8:6-8). This objection fails to grasp fundamental covenantal issues. The law is perfect indeed, but the contextual issue for David in Psalms is that the law is without blemish in and of itself. The contextual issue for the author of Hebrews is that believers now have a "better covenant, which was established upon better promises."

The Greek word behind "better" in Hebrews is kreitton, meaning stronger, nobler, or better (as in Hebrews 1:4). Psalms refers to the law, whereas Hebrews refers to the covenant. There is a strict difference between the law itself and an agreement to follow the law. One represents the terms of the covenant, while the other represents the covenant agreement itself. The skeptical objection entirely ignores this theological difference.
