Thank you for your thoughts on this but let me take it a little farther.
All of God's blessings come with a condition. There is a big "If" attached to them. Isn't the condition here that the churches repent and do what the 2 churches Jesus found favor with do, which is teach about those "which say they are Jews, and are not, but are the synagogue of Satan."
Is that not what the "Spirit sayeth unto the churches"?
My question is, would they not have to do this in order to be "accepted" by Christ. Individual believers, as you say, might be blessed but wouldn't they also have to understand or "hath an ear" to this same teaching in order to find complete favor with Jesus? His last admonition in chapter 3 was to hear what the Spirit said to the churches.
The leaning I have in the Spirit is that the blessings such as for those who overcome wrt Ephesus, i.e. that they will eat from the Tree of Life - and the admonishment to hear what the Spirit says to the churches - applies to each and every Christian. All of the words are food for us.
Also, the leaning I have in the Spirit is that the churches themselves should be seen as assemblies, congregations, groups of Christians - sharing in a common circumstance, fault, ability or challenge. Those who are among the church of Ephesus are those who match that description regardless of when or where they might live or which label they wear or where they worship. Each of us today would relate to one or more of those churches.
As an example, the church of Ephesus was doctrinally pure - careful to be correct in every detail and to put prophets to the strictest of tests. They contended for the faith vigorously and defended His Name. They held up to persecution. But they had a fatal flaw in that they didn't love God (and as a distant second, love their neighbor) as they should. Christ is threatening them collectively and individually - if they don't repent and try to love again, He will remove their candlestick, i.e. quit blessing them as a group. But even if the group fails, a member of that group can nevertheless overcome by repenting and returning to his first love.
Now consider the history of Christianity all the way to this very day - how many groups became obsessively "correct" in their doctrine but failed in their love - and consider how greatly they were blessed and grew and were effective in their work when they loved and how their numbers dwindled and how toothless they became when they did not.
And that phenomenon is true of individuals as well – those who are doctrinally pure but unloving should pay particular heed to what the Spirit says to the church of Ephesus.
That is the Spiritual discernment I have concerning Ephesus – but yours may be quite different, and that’s ok too.
