The minute you were born you did not have a religion until it was brought upon you by family/friends/church. Prove to me why someone needs religion to live their lives. Is there a chance that one could be completely happy and healthy without a book or books telling them how to live? Is the only reason a religious person lives a morally correct life is because they expect a divine reward at the end of their lives?
I'm a Christian, and I believe the reason why we need Jesus in our life is because He can do good things through you, and make you have a better life than the life you have in your sinful nature. It might be hard because being a Christian is really tough because people are constantly testing you and you have to go through trials that I believe God is testing you on. And in order for you to get to Heaven is to enter through the narrow gate. You will end up knowing what is right and wrong from the Creator of the Universe because He established what is right and wrong ,and gave us book on how to live our life. I think it's impossible for someone to live their life without books telling them how to live, because we read a lot of books in our lifetime and sometimes people our looking for hope because they are confused at life and so they try to learn from what they have read in a book and try to apply it to their own life. The reason I believe in Jesus Christ is because He took away my sins, and paid it on the cross. He rose again from the grave proving that He is God and that death cannot conquer Him. Those who believe in Christ and follow what He truly says. They will be granted eternal life in Heaven when they die. You can also accept Jesus Christ as your Lord and Savior and you'll end up going to Heaven if you follow what Christ said.
