1I saw a mighty angel coming down out of the sky, clothed with a cloud. A rainbow was on his head. His face was like the sun, and his feet like pillars of fire. 2He had in his hand a little open book. He set his right foot on the sea, and his left on the land. 3He cried with a loud voice, as a lion roars. When he cried, the seven thunders uttered their voices. 4When the seven thunders sounded, I was about to write; but I heard a voice from the sky saying, “Seal up the things which the seven thunders said, and don’t write them.”
5The angel whom I saw standing on the sea and on the land lifted up his right hand to the sky 6and swore by him who lives forever and ever, who created heaven and the things that are in it, the earth and the things that are in it, and the sea and the things that are in it, that there will no longer be delay, 7but in the days of the voice of the seventh angel, when he is about to sound, then the mystery of God is finished, as he declared to his servants the prophets.
8The voice which I heard from heaven, again speaking with me, said, “Go, take the book which is open in the hand of the angel who stands on the sea and on the land.”
9I went to the angel, telling him to give me the little book.
He said to me, “Take it and eat it. It will make your stomach bitter, but in your mouth it will be as sweet as honey.”
10I took the little book out of the angel’s hand, and ate it. It was as sweet as honey in my mouth. When I had eaten it, my stomach was made bitter. 11They told me, “You must prophesy again over many peoples, nations, languages, and kings.”
Eternal (Gk. αἰώνιος, aionios). (6:23; Matt 19:16; Rev 10:6) Strong's 166
This word is used often throughout the NT. It is an idiomatic way of referring to a long time, time without end or time without beginning or end. The word αἰώνιος (aionios) comes from the word for age, αἰών (aion), which can also refer to time without limit, and from which the English word “eon” comes. Eternity, which is God’s domain, is the absence of time. Humans live forever, which means time without end. Technically, God alone exists in eternity, humans can be said to have life everlasting. This distinction is commonly ignored in everyday speech and Bible translations! Time is the measure of how long it takes for physical things to move in relation one to another (planets or electrons). As long as there are humans, resurrected bodies, the new heaven and earth, there will be time. (Rev 10:6 refers to “no more delay.”) In Jesus, believers live forever, meaning they have everlasting life.
