The Old Testament law, with its sacrifices, was a vital part of God's plan. But what did it really achieve?
Hebrews 10:1 tells us the Mosaic Law was like a "shadow" of good things to come, not the "very image." Think of an artist sketching an outline before painting a masterpiece. The sketch gives you an idea, a hint of what's to come, but it's not the finished work itself.
Similarly, the sacrifices offered under the Law were a shadow. They pointed forward to something greater, something more real. Because they were only a shadow, and not the actual substance of the good things, they could never, by their repeated offerings, make those who drew near to God truly perfect.
This doesn't mean the Law was bad or useless! It served a crucial purpose in revealing God's standard, highlighting our sin, and pointing us to the future fulfillment in Christ. But it was designed to be temporary, a preparatory stage.
