So far I haven't seen the end of the world today, but the number twelve is still pretty significant. From several sources across the net, here's a little bit about 12 in our Bible.
12. It indicates a kind of totality.
The most obvious example of 12 are the 12 tribes of Israel, mentioned many times throughout the Bible. Revelation incorporates multiple uses of 12. After the Tribulation begins, Christians will have already been Raptured to Heaven to spare them the horrors. 144,000 people, 12,000 from each tribe of Israel, will be sealed for God. The New Jerusalem, the city of Heaven, is described as having walls 144 cubits thick, symbolic of the 12 tribes and the 12 Apostles.
The foundations of the walls are made of 12 precious stones. The city is foursquare, with walls 12,000 stadia, or furlongs, long, wide, and high. There are 3 gates in each side, for 12 total. These are made of single pearls, giving us the phrase “pearly gates.” Inside, the Tree of Life yields 12 different kinds of fruits.
Daniel is also concerned with the time of the end, and Daniel has 12 chapters. Daniel 12:12 states, “Blessed is the one who waits for and reaches the end of the 1,335 days.” 1 plus 3 plus 3 plus 5 equals 12.
May you be totally (12) committed and blessed in your waiting for God, whether He comes today or in 144,000 days!
