Revelation 2:1-7
The Message to the Church in Ephesus
1 “Write this letter to the angel[fn] of the church in Ephesus. This is the message from the one who holds the seven stars in his right hand, the one who walks among the seven gold lampstands:
2 “I know all the things you do. I have seen your hard work and your patient endurance. I know you don’t tolerate evil people. You have examined the claims of those who say they are apostles but are not. You have discovered they are liars. 3 You have patiently suffered for me without quitting.
4 “But I have this complaint against you. You don’t love me or each other as you did at first![fn] 5 Look how far you have fallen! Turn back to me and do the works you did at first. If you don’t repent, I will come and remove your lampstand from its place among the churches. 6 But this is in your favor: You hate the evil deeds of the Nicolaitans, just as I do.
7 “Anyone with ears to hear must listen to the Spirit and understand what he is saying to the churches. To everyone who is victorious I will give fruit from the tree of life in the paradise of God.
