If we are sent to Hell can we get a do over?
As Frank points out we will either be with God or we will not, and that is by choice. If we are not with God we are separated from Him which is in and of itself a "Hell" but the reality of hell as we understand it is yet to come.
Right now all of humanity even those that turn away from God or hate him are given his common grace: love, comfort, etc. hell will be without all of those things and no hope of change you will be in permanent isolation and torment. That's why the stakes are so high in our brief lives.
Consider the possibility of that reality and read the following scripture.
The Rich Man and Lazarus
19 “There was a rich man who was clothed in purple and fine linen and who feasted sumptuously every day. 20 And at his gate was laid a poor man named Lazarus, covered with sores, 21 who desired to be fed with what fell from the rich man's table. Moreover, even the dogs came and licked his sores. 22 The poor man died and was carried by the angels to Abraham's side.[a] The rich man also died and was buried, 23 and in Hades, being in torment, he lifted up his eyes and saw Abraham far off and Lazarus at his side. 24 And he called out, ‘Father Abraham, have mercy on me, and send Lazarus to dip the end of his finger in water and cool my tongue, for I am in anguish in this flame.’ 25 But Abraham said, ‘Child, remember that you in your lifetime received your good things, and Lazarus in like manner bad things; but now he is comforted here, and you are in anguish. 26 And besides all this, between us and you a great chasm has been fixed, in order that those who would pass from here to you may not be able, and none may cross from there to us.’ 27 And he said, ‘Then I beg you, father, to send him to my father's house— 28 for I have five brothers—so that he may warn them, lest they also come into this place of torment.’ 29 But Abraham said, ‘They have Moses and the Prophets; let them hear them.’ 30 And he said, ‘No, father Abraham, but if someone goes to them from the dead, they will repent.’ 31 He said to him, ‘If they do not hear Moses and the Prophets, neither will they be convinced if someone should rise from the dead.’”
Do we stop sinning against God or rebelling once we are in Hell? There is nothing to indicate people alter their behavior once there. You see we fil to really understand God's Holiness and his justice. We always are looking for a way out from our sin and bad behavior.
Now is the time to confess your sins (1 John 1:9) and repent, change your behavior before it is too late for you!
