I'm sorry your parents never helped you discover who God is or why He is important. Perhaps their parents did the same -- but whatever the reason, I hope you won't do this with your own children. The Bible says, "Teach them to your children and to their children after them" (Deuteronomy 4:9).
The most important thing I can tell you is that God loves you, and He wants you not only to believe in Him, but also to come to know Him as your friend. How do we know this? We know it because He has demonstrated it to us a multitude of ways. Have you ever thought about the gift of life that God has given you? Have you ever considered the beauty and glory of the world He created? He didn't need to make it this way -- but He did, and He did it so we could enjoy it.
But God has shown His love for us an even deeper way, by coming down to earth in the person of Jesus Christ. Do you want to know what God is like? Look at Jesus, for He was God in human flesh. And when you do, you'll realize just how much God loves you, for He gave His life to save you from your sins.
Don't drift around any longer in a fog of unbelief. Instead, turn to Jesus and invite Him to come into your life. Then ask Him to guide you to a church where you can learn about Him and His will for your life.
