And so John begins receiving his visions.
He was in the Spirit. A proper noun referring to the Holy Spirit. This is a reference to the control of the Holy Spirit over John’s soul, and is the normal function of any believer when they have confessed their sins to God the Father.
John was in the Spirit. He had just confessed his sins, whatever they might have been. Most believers will confess arrogance if nothing else comes to mind, just to cover their bases, so to speak. Anyway, John was in fellowship. Details of this process (confession and fellowship) are found in the 1 Jn., study.
Being in fellowship is extremely important, for it is within the fellowship sphere, that your spiritual life functions. When you commit a sin, you are automatically out of fellowship, and when out of fellowship, your spiritual life does not function. Therefore, you are required to confess your sins to God the Father, in order to get back into fellowship.
John was in fellowship, and it happened to be on a Sunday, referred here as the Lords day. This is not a reference to the Day of the Lord, but the first day of the week, Sunday, commonly referred to as the Lord Day, because of the resurrection occurring on a Sunday morning. The phrase, ‘kuriakos hemera,’ was widely used in the first two centuries A.D., and that is where the ‘Lords Day’ phrase came from.
The loud voice was Jesus Christ, Ezek 3:12, 12-13, 17-18.
The sound ‘like a trumpet’ is a reference not to a trumpet, there was no music here, but this is an expression of clarity. The voice was an actual voice. But the sound was clear, and loud, and easily understood. It was not muffled, or veiled making it difficult to understand. But the voice was clear and crisp.
It was loud. In Revelation, the phrase ‘loud voice’ generally means that what is about to be said or revealed demands a solemnity of attitude and respect, Rev. 5:2,12; 6:10; 7:2,10; 8:13; 10:3; 11:12,15; 12:10; 14:2,15,18; 16:1,17; 19:1,17; 21:3. When you have great respect for someone, then when they walk by, or are in your presence, or begin to speak, then you become instantly quiet, and bring all of your attention and concentration toward them.
And even when the person you respect is not present, but you are reading their words, then you likewise give deference to their words, by maintaining yourself in silence and concentration.
Hummm? Do you suppose that includes Bible study?
