The person of the commission is the Apostle John. The Apostle John mentions himself in the content three times.
The piety of the commissioned. In other words, the devotion to God is in view. Note what John says: I was in the Spirit on the Lord’s day. This speaks of the first day of the week, which is Sunday. After the resurrection of Jesus, this day became the day of worship for all believers. The “Spirit” of the Lord rested upon him. He is dwelling in the spiritual realm. He was about to have things revealed to him concerning the future.
Jesus tells John that he shall receive divine visions. They shall reveal what shall come to pass in the future. John has been specially called for this purpose.
He is instructed to write exactly what he sees because it will be shared with the seven churches. This epistle has been handed down over the centuries for the present-day church.
At this point, John turns to face the direction that the voice is coming from. He sees seven golden candlesticks. The candlesticks are lamps, lamp stands or menorahs. They represent the seven churches. The responsibility of the church and the believer is to be a light to the world. We are like a city set upon a hill, which cannot be hid. Eph. 5:8 and Phil. 2:15.
