Hi Orange County. Life after death is very real. People try to explain away our consciousness, how it "arises" mystically out of our brains. However, the reality is our souls are immaterial. They have no space, no weight or mass. They are spiritual, and will live on after we die.
Jesus explained what the current world is like - people walking around in darkness, because nobody really understands the way. God sent Jesus to be the "light of the world" so that life makes sense. He also came to teach us how to get to heaven.
Modern man claims that there is no such thing as absolute good or evil. But if thats true, it means that there is no real good or evil, which is absurd. There is good and evil, and we will all face the judgement one day.
Nobody is good enough to stand before the Almighty God on that day and win. People lie steal, watch porn, all kinds of things God hates. Just like a judge will throw people in jail for 1 crime despite a lifetime of good, so God will throw people in hell for one sin.
Of course God loves us and desires a way out. So he sent his son Jesus to the world to bear the punishment for our sin by being crucified. I don't totally understand how it works, but God accepts his sacrifice in our place if we will simply accept it ourselves by believing in his work. Jesus explained it like this "God loved the world so much that he sent his only begotten son so that whoever believes in him would not perish but have everlasting life. God did not send his son into the world to condem the world, but so that the world might be saved through him."
God loves you and he made a way for you to live an eternity in paradise. The way there is so simple, all you have to do is believe in him.
Jesus said "ask and you shall receive, seek and you shall find, knock and the door will be opened". If you would like to know about God, you need to ask God to show himself to you and to seek out the truth, whether Jesus is who he said he is. Reading the gospel of John is a good place to start. For more evidence, William Laine Craig has some good stuff about it. there is nothing more important in life than knowing God. You can't learn to code if you don't spend time coding. Similarly you won't get to know God if you never look for him.
