How do we know that Christ fulfills the Law and the feasts?

In the New Testament, particularly 2 Corinthians 3:14-16, Paul teaches that the veil over the hearts of those reading the Old Testament is removed in Christ. This indicates that the rituals and feasts, such as the Feast of Tabernacles, serve as shadows pointing to a greater reality found in Jesus Christ. His coming was to fulfill the Law, satisfying all the requirements through His perfect life and sacrificial death. Thus, as believers, we are not bound to observe these feasts in a literal sense, but rather we celebrate their fulfillment through Christ, recognizing Him as the true Tabernacle and the ultimate source of our spiritual nourishment.
