Revelation 2:7 “He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes I will give to eat from the tree of life, which is in the midst of the Paradise of God.”’
This is the first of the “He who has an ear,” promises the Lord makes to the churches. First we should note that the promises the Lord makes here are to the churches, plural. Not just Ephesus, but Smyrna, etc., all benefit from the hearing and fulfilment of this promise, just as Ephesus benefits from Smyrna’s, etc.
