What does the Bible say about being judged for not observing the law?

In Colossians 2:16-17, the Apostle Paul teaches that believers should not allow anyone to judge or condemn them over matters like food, drink, or observance of certain days. This is because these regulations were merely shadows of what was to come, with the true substance being found in Christ. If one is in Christ, they have all they need for righteousness and should not be troubled by external judgments that do not align with the gospel, which gives all glory to Christ and none to man.
