The churches are criticized for: abandoning their first love, following other teachings, tolerating spirits of enticement and sexual immorality, eating food sacrificed to idols, not completing their deeds in the sight of God, for being luke warm, that is, wretched, blind, poor and naked.
The churches are praised for: Patient endurance, toil, sound doctrines, hating the Nicolaitans, having affliction and poverty, yet realizing they are rich, remaining true to His name, deeds, love and faith, perseverance, doing more, keeping His Word and not denying His Name, and enduring patiently.
These all should be used on a daily basis to shape the church and the individual, that is, using the criticism to make us better and showing us what to guard against. All the praise should be used to show us what we need to continue doing. The most important thing is not to abandon our first love, that is Jesus Christ. If we are close to him, continually persuing and increasing our relationship with Him, praying for guidance and studying His Word, then the other things should fall into place. We need to keep all these things in mind and check ourselves often to be sure we are remaining faithful to His Word and direction.
