This passage in Hebrews, (Hebrews 10:1-4) shows us that there was no lasting solution in the daily and annual sacrifices under the Law. For if these sacrifices truly cleansed, they would have been sufficient to purify. But instead, they stood more as a guilty reminder of sin. It was only Christ’s sacrifice that was perfect and final…eliminating the need for repeated sacrifices and highlighting the total inadequacy of man to achieve sinlessness on his own. Psalm 40:6-8 shows us that Christ’s sacrifice was once for all, and thus we can be sanctified and made holy by His offering on the Cross. (Hebrews 10:10)
