In preparation for the Passover, believers are urged to practice sincere self-examination as instructed in I Corinthians 11:28, recognizing that while faults may appear, no one can make himself worthy; rather, by judging ourselves we avoid divine judgment and gain the opportunity to repent and change. Within this spirit, the warning of Revelation 2:4—recorded by the apostle John during the late first century under the reign of Domitian calls believers to return to their "first love," the foremost sacrificial devotion (agapē) for God. Addressed first to the church at Ephesus, long influenced by Paul, the message shows that even faithful works and doctrinal vigilance cannot replace wholehearted love, which fulfills the greatest commandment taught by Jesus Christ in Gospel of Matthew 22:37-40. Christ's remedy is to remember, repent, and return to the works born of that first devotion, ensuring that faith, service, and perseverance flow from a renewed and maturing love for God.
