But I have against you that you left your first love. (Revelation 2:4 MKJV)
The Ephesians were very diligent in searching the scriptures and testing what others said. They made sure their doctrine was pure. They didn’t allow anything that was not pure. They had nothing to do with pagan worship. They were busy preaching the Gospel. But something went wrong. They were doing the work of God but forgot the God of the work. They were so diligent about keeping pure and working for the Lord they forgot to spend time with Him. They were so diligent about keeping evil out of the church they forgot to love others. Are we so busy working for God that we forget the God of the work? Are we spending less time in prayer and Bible study?
