3:13 `He who has an ear, let him hear what the Spirit says to the churches.'

He who has an ear, let him hear what the Spirit says to the churches.

The route of the letters to the churches is amazing. While it appears that the route is through many agents, it really was directly from the Holy Spirit/Lord all the time.

Hearing is a process of living people NOT dead. Therefore, the Spirit is communicating to people who are alive. That is not unusual.... 1 Corinthians 14:26-33 indicates it is the spirit of the prophets who communicate from a God of order and not confusion.
