The SECOND coming of Christ would not be possible if he did not arrive on earth the first time. The first coming of Jesus, who lived on earth from 5 B.C. to 30 A.D., was for the purpose of living a perfect life then dying as the perfect sacrifice for sin in order that man might live forever. It is during his last physical appearance to his disciples, on May 18, 30 A.D., that he ascends to heaven (Matthew 28:18 - 20; Mark 16:15 - 20; Luke 24:49 - 53; Acts 1:4 - 11). Right after he ascends out of sight two angels declare that Jesus will return to earth in the same way that he left. It is this return to earth that is commonly referred to as the Second Coming.
Some denominations believe Jesus' words about a second coming are only a metaphor. They therefore teach that any statements regarding his return should not be taken literally. Others accept the prediction of his return to earth literally, and many have spent considerable effort in speculating on just when this event would happen. Many churches, pastors, Biblical teachers, and students of the Bible have spent countless hours and dollars in a foolish effort to pinpoint exactly when Christ will be coming from heaven to rule the earth.
EVERY prediction regarding Jesus' return has miserably FAILED. Jesus himself stated that NO man or even an angel, NO ONE except God the Father, knows the day or the hour of his return (Matthew 24:26). God's word does not offer exact dates for end-time events but rather presents the overall structure of what will occur before His Son's return. Sadly, many ministries have used their 'knowledge' of when Jesus returns, coupled with other prophetic speculations, to attract new members to their group and greatly increase their income.
Scriptures state there are several events that must occur before the second coming of Jesus Christ. Some of these, found in the book of Revelation, are the Great Tribulation, the heavenly signs and the Day of the Lord.
The TRUE second coming or return of the Lord is delineated in chapter 19 of Revelation. His arrival on earth will be as King of Kings and Lord of Lords (Revelation 19:16). He will come with the power of God to save mankind from total destruction and to usher in the Kingdom of God on earth. He will also resurrect all those who ever lived who received God's Holy Spirit and lived a life of overcoming. The resurrected righteous will receive immortality and rule the earth with Jesus for one thousand years (also known as the Millennium, see Revelation 20).
