Some believe, as the Jehovah's Witnesses do, that many will get a second chance after death. The Bible never mentions people having a second chance at life. The Scriptures clearly tells us that "it is appointed for man to die once, and after that comes judgment." (Hebrews 9:27 ESV) Jesus told the criminal on the cross, "Truly, I say to you, today you will be with me in Paradise."(Luke 23:43 ESV), not "You will have another chance to live a life on this earth." In Matthew 25:46 we are told that some "will go away into eternal punishment, but the righteous into eternal life." (Matthew 25:46 ESV) This tells us that believers get eternal life while unbelievers get eternal punishment.
The Bible also makes it clear that the resurrection of believers and unbelievers has not yet occurred, meaning that the bodies of the deceased are still in the grave.
"I tell you this, brothers: flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. Behold! I tell you a mystery. We shall not all sleep, but we shall all be changed, in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we shall be changed. For this perishable body must put on the imperishable, and this mortal body must put on immortality. When the perishable puts on the imperishable, and the mortal puts on immortality, then shall come to pass the saying that is written: 'Death is swallowed up in victory.'" (1 Corinthians 15:50-54 ESV)
"But we do not want you to be uninformed, brothers, about those who are asleep, that you may not grieve as others do who have no hope. For since we believe that Jesus died and rose again, even so, through Jesus, God will bring with him those who have fallen asleep. For this we declare to you by a word from the Lord, that we who are alive, who are left until the coming of the Lord, will not precede those who have fallen asleep. For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first. Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord." (1 Thessalonians 4:13-17 ESV).
At death, the Bible says that deceased believers are with the Lord. "So we are always of good courage. We know that while we are at home in the body we are away from the Lord, for we walk by faith, not by sight. Yes, we are of good courage, and we would rather be away from the body and at home with the Lord." (2 Corinthians 5:6-8 ESV)"I am hard pressed between the two. My desire is to depart and be with Christ, for that is far better." (Philippians 1:23 ESV) This is further confirmed by John. "When he opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the witness they had borne." (Revelation 6:9 ESV)
So, believers in heaven exist in non-bodily form, (i.e. spiritually/non-corporeally) waiting the resurrection. When an unbeliever dies, he also exists in a non-bodily/spiritual/non-corporeal form, but he is not in Heaven, but Sheol/Hades, the realm of the dead. Believers are resurrected at the Second Coming, and unbelievers are raised at the final judgment after the Millennium. Hades will be emptied before the Great White Throne, where its occupants will be judged.
Thus no one has a second chance at death. All wait, either waiting with the Lord or in Hades, until the Last Day when they are resurrected to face their Maker. Hopefully we are ready for this day by being found in Christ!!
