Why is Christ's sacrifice crucial for our worship?

Our access to God and the acceptance of our worship hinges on Christ's sacrifice. As detailed in Hebrews 13:15, the Bible states that we must offer the sacrifice of praise through Him. This indicates that any offering we bring is sanctified only through Christ. The altar itself sanctifies the gift; without Christ, no gift or praise would be worthy in God's sight. Thus, recognizing Christ as our altar underscores the necessity of His redemptive work for our worship to be pleasing to God.
