REVELATION 1:10

I was in the Spirit on the Lord’s Day, and heard behind me a great voice, as of a trumpet.

The ‘Lord’s Day’ is that significant period that will transpire just before the end of the world and the Second Coming of Jesus.

The apostle Paul indicated the Second Coming of Jesus and the resurrection of the righteous to take place on the day of the Lord. He wrote, “For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. 16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: 17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord. 18 Wherefore comfort one another with these words. 1 But of the times and the seasons, brethren, ye have no need that I write unto you. 2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.” (1 Thessalonians 4:15-18; 5:1, 2) Peter wrote of the destruction of the earth and heavens to take place on ‘the day of the Lord’, “But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.” (2 Peter 3:10)

The prophets of the Old Testament, especially the minor prophets, prophesied extensively of ‘the day of the Lord’ as the day of His wrath and destruction. Isaiah prophesied, “Behold, the day of the LORD cometh, cruel both with wrath and fierce anger, to lay the land desolate: and he shall destroy the sinners thereof out of it.” (Isaiah 13:9) Joel prophesied, “Alas for the day! for the day of the LORD is at hand, and as a destruction from the Almighty shall it come.” “Blow ye the trumpet in Zion, and sound an alarm in my holy mountain: let all the inhabitants of the land tremble: for the day of the LORD cometh, for it is nigh at hand;” (Joel 1:15; 2:1) “The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining: 11 And the LORD shall utter his voice before his army: for his camp is very great: for he is strong that executeth his word: for the day of the LORD is great and very terrible; and who can abide it?” (Joel 2:10,11) Zephaniah prophesied, “The great day of the LORD is near, it is near, and hasteth greatly, even the voice of the day of the LORD: the mighty man shall cry there bitterly. 15 That day is a day of wrath, a day of trouble and distress, a day of wasteness and desolation, a day of darkness and gloominess, a day of clouds and thick darkness, 16 a day of the trumpet and alarm against the fenced cities, and against the high towers. 17 And I will bring distress upon men that they shall walk like blind men, because they have sinned against the LORD: and their blood shall be poured out as dust, and their flesh as the dung. 18 Neither their silver nor their gold shall be able to deliver them in the day of the LORD's wrath; but the whole land shall be devoured by the fire of his jealousy: for he shall make even a speedy riddance of all them that dwell in the land.” (Zephaniah 1:14-18)

Therefore, when John wrote that he was ‘in the Spirit on the Lord’s Day’, he was conveying the truth that he had been transported by the Spirit into the Lord’s Day, that significant period that will transpire just before the end of the world and the Second Coming of Jesus.

Immediately after John had been transported by the Spirit into the Lord’s Day, he heard ‘a great voice as of a trumpet’. The sound of a trumpet is clear and distinct.
