Why?
This is really the ultimate question. Why do we exist? What is the meaning of life? God is very clear about this and He wants everyone to know, including you. He wrote His word the Bible and preserved it for you today, so you can know who He is.
God created our universe, everything you see and know. He created not just matter and energy, but information including the ability for you to reason and know who He is. He created a perfect world with only one law that couldn't be broken. The first of his creation chose to break that law and mankind has been breaking God's commands ever since.
Breaking God's law is a serious thing, and by his law, we each deserve eternal damnation for our actions. He is Just, but He is also Loving and has provided a way for us to be made right with him. He did this by sending his son Jesus to die and take the penalty for our sin. Jesus conquered death and invites us to put our faith in Him as the only one who can restore us.
We are one of many groups of believers who meet together to learn more about God and the truth of His word. The joy of knowing we are right with Him is something wonderful that we want everyone to know about.
