I used to wonder why different timeframes were given for the arrival of Jesus.
In the parable of the virgins who waited for the bridegroom, the bridegroom arrived at midnight. In Luke 12:38, He comes at the second, or third watch. Then I noticed that the ones waiting in the passage from Luke were servants, not virgin brides.
Compare these two passages starting with the parable of the virgins/brides.
Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom. And five of them were wise, and five were foolish. They that were foolish took their lamps, and took no oil with them: But the wise took oil in their vessels with their lamps. While the bridegroom tarried, they all slumbered and slept. And at midnight there was a cry made, Behold the bridegroom cometh; go ye out to meet him. Then all those virgins arose, and trimmed their lamps. And the foolish said unto the wise, Give us of your oil; for our lamps are gone out. But the wise answered, saying, Not so; lest there not be enough for us and you: but go ye rather to them that sell, and buy for yourselves. And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door (which opens in heaven at the Rapture) was shut. Afterward came also the other virgins, saying Lord, Lord , open to us. But he answered and said, Verily I say unto you, I know you not.
Now compare that with Luke:
35 "Be dressed ready for service and keep your lamps burning, 36 like men waiting for their master to return from a wedding banquet, so that when he comes and knocks they can immediately open the door for him. 37 It will be good for those servants whose master finds them watching when he comes. I tell you the truth, he will dress himself to serve, will have them recline at the table and will come and wait on them. 38 It will be good for those servants whose master finds them ready, even if he comes in the second or third watch of the night. (Emphasis added).
My own thought is that there two seperate events. Just what I think.
