Some day the invitation to heaven will cease without warning (1 Thes. 5:2) and those who didn't accept it will never get another chance for all eternity (Luke 14:24). There won't be a redo...ever. On that day the last plane will part and all of those that got on it will join those who have gone before, rejoicing with God and all others present at the largest, most celebrated banquet mankind has ever seen where all wrongs will be righted, suffering will cease, all tears will be wiped away, and all joy will be made full.
Don't let your own prejudices cause you to not investigate this for yourself. Regardless how you feel about us/me, one thing you can be certain about with your own eyes regardless of your beliefs is your existence here won't last forever. If the idea of dwelling with God who loves you immensely doesn't draw you in, let the fear of the alternative be enough that you investigate getting eternity-insurance, and do so without delay. For the day your invitation will be revoked could be soon and on that day the free gift of eternal life will no longer be offered. When heaven's gates are closed, they're closed.
"Once the head of the house gets up and shuts the door, and you begin standing outside and knocking on the door, saying, ‘Lord, open up to us!’ and He then will answer and say to you, ‘I do not know where you are from.’ Then you will begin saying, ‘We ate and drank in Your presence, and You taught in our streets!’ And yet He will say, ‘I do not know where you are from; leave Me, all you evildoers.’ In that place there will be weeping and gnashing of teeth when you see Abraham, Isaac, Jacob, and all the prophets in the kingdom of God, but yourselves being thrown out. And they will come from east and west, and from north and south, and will recline at the table in the kingdom of God. - Luke 13:25-29
