What does the Bible say about the shadow of the law?

In Hebrews 10:1, it is noted that the law has a shadow of good things to come but is not the substance or image of those things. It serves to highlight God's holiness and humanity's depravity, revealing our need for a Savior. The sacrifices of old could never completely atone for sin, as they are mere reminders of guilt rather than actual solutions. This illustrates the inadequacy of relying solely on the law for salvation, pointing instead to the perfect sacrifice of Christ, the true image that fulfills God's requirements.
