Chapters 2 & 3 of Revelation include the seven letters to the seven churches which include, Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia, and Laodicea. There are some things we do not fully understand in these letters, but there are some things that are very clear. The Lord knows what is going on in His churches because He is standing in their midst. Each of the letters encourage believers to overcome. The Lord gives time and calls people to Himself, but people choose to go their own way. Believers will suffer, and it may even get harder, but the time of testing is limited. In these letters the Lord is calling His church to repent of their sin and turn to Him. Jesus is standing at the door of the church, and He said, "Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come into him and have a meal with him, and he with Me" (3:20). The question is to all the churches, "Do we have ears to hear what the Spirit says to the churches?"
