Four
Rosh Hashanna is also known as the Feast of Trumpets; evidently because respective ceremonial trumpets are sounded. Please observe the following references closely:
1 Cor. 15:51,52: 51Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, 52In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
1 Thes. 4: 15-17: 15For 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. 16For 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: 17Then 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.
Such notice will be given at some point during the upcoming Rosh Hashanna/Feast of Trumpets. We cannot anticipate more specifically when it will occur; hence the text: "But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father." (Mark 13:32; Matthew 24:36). Whether everyone will hear it, or only professed Christians, neither have we discerned. At least however, we anticipate professed Christians will hear!
In any case (whether everyone hears, or only Christians) following is what we suppose will happen: Those who have heard, as above, and are "looking to the Lord" should immediately and absolutely drop everything!! Within a short time - we believe no more than a couple of hours (and possibly only a few minutes!) - the Rapture will occur!"
Whoever else may hear the "call," but neglect to get ready for the Rapture, will be running a (tragic) risk of staying behind! It seems the parable of virgins relates our present context:
Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom.
2And five of them were wise, and five were foolish.
3They that were foolish took their lamps, and took no oil with them:
4But the wise took oil in their vessels with their lamps.
5While the bridegroom tarried, they all slumbered and slept.
6And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him.
7Then all those virgins arose, and trimmed their lamps.
8And the foolish said unto the wise, Give us of your oil; for our lamps are gone out.
9But the wise answered, saying, Not so; lest there be not enough for us and you: but go ye rather to them that sell, and buy for yourselves.
10And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut.
11Afterward came also the other virgins, saying, Lord, Lord, open to us.
12But he answered and said, Verily I say unto you, I know you not. (Matthew 25:1-12).
