Many Christian prophecy teachers (and students) believe that the Psalm 83 War can happen before the war described in Ezekiel 38, and all who are Pre-tribulation Premillennialists agree that the Rapture can happen at any moment.
In the Holy Bible, the last 7 years before Jesus returns are referred to as the Tribulation. This period of time begins when the AntiChrist confirms a peace treaty between Israel and the nations or the many people other than Israel. This man will appear to be a peace maker, but according to God's word he will be a liar and will destroy many with peace. 3 1/2 years after the peace treaty is confirmed he will enter the rebuilt Jewish Temple in Jerusalem and declare himself to be God, and will perform apparent 'miracles' that many will marvel at, but in reality, he will be filled with the spirit of the Devil himself. It will be Hell on Earth during the last 3 1/2 years before Jesus returns.
When Jesus returns He will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.
If you haven't yet put your trust in Jesus, do so while there is still time. God is a loving God, but also a God of justice and righteousness. In a quiet place, confess to God that you are a sinner because you have broken His laws and that you want His forgiveness by receiving His free gift of salvation. Seek the truth and you will find it. Jesus Christ paid the price for your sin with His very blood, believe it. He died for you but He also conquered death and rose from the dead. Ask God to show you that He is Faithful and True and you too will step into eternal paradise at the appointed time.
