The Rapture

The purpose in all the foregoing is to awaken the sleeping saints. "And that, knowing the time, that now it is high [already] time to awake out of sleep: for now is our salvation nearer than when we believed. The night is far spent, the day is at hand." Rom. 13:11, 12.
About forty years after the rejection by the nation of the person, word, and work of Christ, the city and the temple of Jehovah were destroyed by Titus. Israel's being set aside by God brings in a dispensation of grace to whosoever would receive Jesus.
The particular purpose in bringing this to your attention is this: there is no definite point in time assigned to the "rapture," the resurrection of the dead saints and the changing of the living to bodies of glory. This will mark the end of the day of God's grace and the end of the work of the Holy Spirit in gathering to the body of Christ that which is known as the assembly.
The rapture will definitely close the present day of God's grace. Those remaining on the earth will be subject to the conditions of "the great tribulation" which will be increasingly severe until the end of the seven years. Then the Lord Jesus Christ (Messiah) will come out of heaven to begin the work of judgment that will restore Israel to their long-promised time of blessing, and inaugurate the reign of righteousness that will bring peace and blessing to this troubled world.
