History has it that this event occurred in AD66. Jerusalem was besieged by the Romans and the Christians remembered the words of Jesus. They fled as soon as the gates of the city were opened briefly and not one of them was hurt.
The siege Jerusalem was under got so bad that people began to starve to death and some women even killed and ate their babies. In AD70 when the Romans gain entry into the city, most of the Jews fled into the temple and a fire broke out that raised it to the ground and killing some Jews in the process. About a million Jews were slaughtered and only about 100,000 survived. If the siege had gone on any longer it would have likely wiped out all the Jews.
The rest of Jesus’ words covered His return and the end of the world. Jesus did mention that 2 people will be together and one of them shall be taken will the other left and this has been used to teach the rapture doctrine. However, what really does that word taken mean? The original Greek word from which it was translated actually means ‘to be associated with’. It implies recognition and acceptance and does not conjure any impression of being spirited away someplace.
1 Thessalonians 4 is also used in support of the doctrine because of the use of the words ‘caught up’
15 We tell you this directly from the Lord: We who are still living when the Lord returns will not meet him ahead of those who have died. 16 For the Lord himself will come down from heaven with a commanding shout, with the voice of the archangel, and with the trumpet call of God. First, the believers who have died will rise from their graves. 17 Then, together with them, we who are still alive and remain on the earth will be caught up in the clouds to meet the Lord in the air. Then we will be with the Lord forever.
Caught up here is translated from the Greek word harpazo which means to ‘to carry off by force’. This same word was also used to describe how people gain entrance into the kingdom of heaven
And from the days of John the Baptist until now the kingdom of heaven suffers violence, and the violent take it by force. Matthew 11: 12
It does not refer to a ‘rapture’ but to taking possession of something and making it yours. Jesus will descend to make the church His! When He descends at His second coming, those who have died in Him shall be resurrected as per 1 Corinthians 15 and those who are alive shall be transformed and together with the Old Testament ‘cloud’ of witnesses shall be with Him.
