I personally believe in God, I believe he has a name which is Jehovah and its found in Psalms 83:18, I also believe in his son Jesus Christ, who died for our sins so that we can have the hope of everlasting life. Jehovah gives us free will because he doesn't want to force anyone to serve Him if they don't want to. I believe that prayer truly works. There has been times in which I was going through a hard time and by praying I was able to get through it. I don't look down on people who don't believe in God, because thats just wrong and judgemental. The bible gives practical advice, even to young people. In 1 Cor. 15:33 it says "Do not be misled, bad association spoils useful habits." Basically saying, those people who are a bad influence on you will take away your good qualities.
Many people read the bible, but don't realize how much wisdom it has in it. You don't have to be a Christian to read the bible.
