Being a Christian isn't about following religious traditions, obeying the ‘golden rule’, or attending church services. It's about knowing and trusting Jesus and finding forgiveness and life in Him.
Christians believe that Jesus is like no other person who ever lived or will live. His life is unlike anyone else's because he alone always lived God's way. And his death by execution on a cross was like no other because it brought life and forgiveness to the world. Jesus life and death was to show God's love for us:
This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. (1 John 4:10 NIV)
