Not long before his death, Jesus established the fact that he would return to earth at some point in the future. Jesus told his disciples, “Let not your hearts be troubled. Believe in God, believe also in me. In my Father’s house are many rooms If it were not so, would I have told you that I go to prepare a place for you? And if I go and prepare a place for you, I will come again and will take you to myself, that where I am you may be also” (John 14:1-3). Although Jesus assured his followers that he would come back for them, the timing of Christ’s return was not revealed to them. Jesus said:

But concerning that day and hour, no one knows, not even the angels in heaven, nor the Son, but the Father only. For as were the days of Noah, so will be the coming of the Son of Man. For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day when Noah entered the ark, and they were unaware until the flood came and swept them all away, so will be the coming of the Son of Man. Then two men will be in the field; one will be taken and one left. Two women will be grinding at the mill; one will be taken and one left. Therefore, stay awake, for you do not know on what day your Lord is coming. But know this, that if the master of the house had known in what part of the night the thief was coming he would have stayed awake and would not have let his house be broken into. Therefore you must be ready, for the Son of Man is coming at an hour you do not expect. (Matthew 24:36-44)

Jesus described the future rapture of believers in terms of being taken or left. The Greek word that is translated taken, paralambano (par-al-am-banˊ-o) means “to receive near i.e. associate with oneself (in any familiar or intimate act or relation); (by analogy) to assume an office” (G3880). Paralambano is the word Jesus used when he said, “I will come again and will take you to myself” (John 14:3). Paralambano is derived from the words para, which means “immediate vicinity or proximity” (G3844), and lambano, which means “to take” (G2983).

Jesus encouraged his followers to stay awake because they did not know when he would return. In his parable of the ten virgins, Jesus indicated that the ten virgins represented the kingdom of heaven and explained that because the bridegroom was delayed the virgins became drowsy and slept (Matthew 25:1-5). Jesus had previously identified himself as the bridegroom (Matthew 9:15; John 3:29) and indicated in his parable of the ten virgins that the bridegroom’s return was linked to the marriage feast (Matthew 25:10). The marriage feast represents the physical union of Christ with his church. This event takes place in Revelation 19:7. Immediately following this event, Revelation 19:11-21 tells us that Jesus will return to the earth and will “strike down the nations and he will rule them with a rod of iron” (Revelation 19:15). Revelation 19:16 states, “On his robe and on his thigh he has a name written, King of kings and Lord of lords.”

Revelation 19:9 suggests that those who participate in the marriage supper of the Lamb will receive God’s favor in ways that others do not. This may have been why the “Thessalonian believers were concerned that those believers who had already died would miss Christ’s coming. Paul assured them that those who had died would be be caught up to meet the Lord just like those who are alive at his coming (1 Thessalonians 4:13-18)” (Introduction to the First Letter of Paul to the Thessalonians). Paul stated:

But we do not want you to be uninformed, brothers, about those who are asleep, that you may not grieve as others do who have no hope. For since we believe that Jesus died and rose again, even so, through Jesus, God will bring with him those who have fallen asleep. For this we declare to you by a word from the Lord, that we who are alive, who are left until the coming of the Lord, will not precede those who have fallen asleep. For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first. Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord. Therefore encourage one another with these words. (1 Thessalonians 4:13-18)

Paul used the term fallen asleep or koimao (koy-mahˊ-o) in the Greek to refer to those who had died after believing in Christ. Paul was referring to the body being asleep, not the soul (note on 1 Thessalonians 4:15). Paul explained in his letters to the Corinthians that the believer’s body is a temporary home that will be replaced by an eternal one when the rapture occurs (2 Corinthians 5:1-5). Paul said, “We shall not all sleep, but we shall all be changed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we shall be changed. For this perishable body must put on the imperishable, and this mortal body must put on immortality” (1 Corinthians 15:51-53).

Paul indicated that the rapture of the church will take place in a moment, in the twinkling of an eye (1 Corinthians 15:52). Paul also stated that “the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God (1 Thessalonians 4:16). This critical transition will not only signal the end of the age of grace but will also usher in the great tribulation and the beginning of God’s judgment of the world. This time period is known as the Day of the Lord. Paul said, “Now concerning the times and the seasons, brothers, you have no need to have anything written to you. For you yourselves are fully aware that the day of the Lord will come like a thief in the night. While people are saying, ‘There is peace and security,’ then sudden destruction will come upon them as labor pains come upon a pregnant woman, and they will not escape” (1 Thessalonians 5:1-3). The sudden shift from God’s grace being freely offered to judgment and destruction will catch everyone off guard and will result in a great multitude from every nation turning to Christ and the final harvest of the earth (Revelation 7:14; 14:14-20).
