Why is Jesus' birth so important to christians?

Because hes the one who put us on the earth and died on the cross so are sins could be washed away. He is the one who gives us everything we ask for. Jesus is the Son of God. In The Bible, John 3:16 it says, "For God so loved the world, that He gave His only begotten Son. That whoever believes in him shall not perish, but have everlasting life." God saw that no-one was good enough to enter heaven on their own goodness because no-one is truly good enough. We all sin and that would keep us from entering heaven. God sent his only son to earth so that those that believe that he is the son of God and believe that he took our sins upon himself and that he suffered and died for you and me and we accept him as our savior, we are guaranteed to live eternally with him in heaven. There are no strings attached. No money to raise. No list of things to accomplish. Just believe and accept him as your savior. Easy as can be. Jesus has made a miraculous change in my life. He may not give us everything that we ask for as the post above mine says, but he will give us everything that we need. He will never leave you or forsake you. I promise.
