What does the Bible say about leaving our first love?

In Revelation 2:4, Jesus addresses the Church of Ephesus, stating, "I have somewhat against thee, because thou hast left thy first love." This reflects a common issue within the church where believers can become diligent in their works yet neglect their foundational love for Christ. The exhortation to remember from where they have fallen calls for repentance and a return to their initial passion, emphasizing that good works must flow from a heart that loves Christ deeply. This message is vital for Christians today, reminding them that the motivation for service must always stem from love for God, as demonstrated by the woman who washed Jesus's feet in Luke 7.
