The church in Ephesus was on fire! They loved God, the church was growing rapidly and they had so much faith. Paul writes down several prayers in this letter. Most notable is Eph 3:14-21. Reminding them to not neglect the inner person. Continuing to Grow in their love for God. 40 years later in the book of revelation we see that they have neglected this very thing. And God tells them to remember what their faith and love were like 40 years earlier – and tells them to repent.
This is a beautiful study of reminding us to keep our priorities right
