The Biblical Rapture
According to the Bible there will be a future time when all of the believers in Jesus Christ are taken off of the earth to heaven to be protected from the time of terrible tribulation known as the Day of the Lord. This miraculous rescue is described in a number of Biblical passages such as Matthew 24:36-42,
"But of that day and hour no one knows, not even the angels of heaven, but My Father only. But as the days of Noah were, so also will the coming of the Son of Man be. For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and did not know until the flood came and took them all away, so also will the coming of the Son of Man be. Then two men will be in the field: one will be taken and the other left. Two women will be grinding at the mill: one will be taken and the other left. Watch therefore, for you do not know what hour your Lord is coming."
And also 1 Thessalonians 4:16-17,
"For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air..."
