What does it mean that the gospel is a memorial?

The gospel acts as a memorial, reminding both the church and the world of the redemptive work accomplished by God through Christ. Just as the trumpets in Numbers were used to declare God’s faithfulness and the covenant with His people, preaching the gospel memorializes and highlights what God has done for sinners. It serves to proclaim His grace continually, directing the focus away from human efforts and back to God's actions on behalf of His people. This gospel remembrance is crucial for maintaining the faith and assurance of believers in Christ's completed work.
