Matthew 24:40 Then shall two be in the field; the one shall be taken, and the other left.
Why are there so many different opinions about the rapture. Here is a warning directly from Jesus. it sounds scary but in reality it is a comforting warning:
[Luk 21:8-19, 25-27 KJV] 8 And he said, Take heed that ye be not deceived: for many shall come in my name, saying, I am [Christ]; and the time draweth near: go ye not therefore after them. 9 But when ye shall hear of wars and commotions, be not terrified: for these things must first come to pass; but the end [is] not by and by. 10 Then said he unto them, Nation shall rise against nation, and kingdom against kingdom: 11 And great earthquakes shall be in divers places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven. 12 But before all these, they shall lay their hands on you, and persecute [you], delivering [you] up to the synagogues, and into prisons, being brought before kings and rulers for my name's sake. 13 And it shall turn to you for a testimony. 14 Settle [it] therefore in your hearts, not to meditate before what ye shall answer: 15 For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist. 16 And ye shall be betrayed both by parents, and brethren, and kinsfolks, and friends; and [some] of you shall they cause to be put to death. 17 And ye shall be hated of all [men] for my name's sake. 18 But there shall not an hair of your head perish. 19 In your patience possess ye your souls. ... 25 And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring; 26 Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken. 27 And then shall they see the Son of man coming in a cloud with power and great glory.

TOJ #143: Believers living at the time of the end will be raptured. [MT 24:31&40-41//LK 17:30-35] “Raptured” means translated to heaven without experiencing death. Paul also mentioned this phenomenon (in 1CR 15:51 & 1THS 4:17).
TOJ #144: Only God the Father knows when the end will come. [MT 24:36//MK 13:32] Some people might find it disconcerting that Jesus could be mistaken or ignorant about the exact time salvation history will end, but they should realize that He was human (1TM 2:5) and had finite capabilities, which is the reason His moral perfection qualified Him to be Messiah (HB 2:17-18, 4:15, 5:7-9). If Jesus did not know, Believers in Him certainly should not be concerned with the date {ACTS 1:7}. (See TOJ #57.)
TOJ #145: The omega event will be unexpected. [MT 24:27&37-39//LK 17:24&26-27, LK 12:39-40, 17:28-29] Paul also taught this (in 1THS 5:2-6). Thus, the need for the next TOJ.
TOJ #146: Be prepared. [MT 24:42-44//MK 13:33-37, LK 12:35-40, 21:34-36] This is the explicit significance of the previous TOJ, and how to be ready is explained in the next one. Readiness is signified by oil in the Parable of the Ten Virgins. {MT 25:1-13}
TOJ #147: Readiness consists of being good stewards of God’s gifts. [MT 24:45-51] In the Parable of the Ten Virgins, readiness is signified by having lamp oil, which might symbolize good deeds (JM 2:17, EPH 2:10) {MT 25:1-13, LK 12:35}, and in the Parable of the Talents, the monetary talents represent any resource, ability or opportunity a person possesses. {MT 25:14-30//LK 19:12-27} The “more” that is given to the person who does well with what he/she “has” may include temporal blessings, but it certainly refers to blessings in heaven.
