It was a typical morning in the Temple of Jerusalem around the time of Jesus. The priests were sleeping in second-floor chambers above the colonnade surrounding the outer court of the Temple. Shortly after the rooster crowed, the officer of the day knocked on the door. He conducted the casting of lots to determine those who would do the various duties of the daily service.
At daybreak they brought a lamb to the outer court. While the priest prepared to slaughter the lamb, another entered the Temple to clear the ashes from the altar of incense and relight the lamps inside the holy place (cf. Rev. 1:12-16). The opening of the great entrance door into the Temple (cf. Rev. 4:1) was the signal to slay the lamb (cf. Rev. 5:6-10). Priests then brought the body parts of he lamb to the altar of burnt offering and poured out its blood at the base of the altar (cf. Rev. 6:9-11).
The appointed priest then took the golden censer (cf. Rev. 8:3-5). It was like a frying pan with a long handle and had a lid on it. The priest filled it with coals from the hottest part of the fire on the altar of burnt offering (cf. verse 3). He then entered the open door of the Temple and arranged the coals of fire on the altar of incense. At the time commanded by the officer of the day, he added incense to the fire on the altar (cf. verse 4).
At this decisive point in the service three things happened. Someone threw a shovel down (cf. verse 5) between the altar of burnt offering and the entrance to the Temple. A break in the singing of the Temple choir produced a moment of silence (cf. verse 1). And during that moment of silence seven priests would blow seven trumpets (cf. verses 2, 6).
John based the first third of the book of Revelation on the tamid, the daily sacrifice in the Temple. The incense represents the righteousness of Christ applied to the prayers of the saints throughout the Christian Era. This scene assures us that the perfect righteousness of Christ covers our mistakes and even the inadequacy of our good deeds.
Lord, thank You for the assurance that I can be right with You today, no matter how inadequate I may feel.
