For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord. (Romans 6:23 ESV)
Either by willful commission or apathetic omission each of us sin. We do the wrong things, or we choose not to do the right thing. But our sin is not the central message of the Bible.
If sin were the main theme of the Bible it would be a book primarily focused on morality. And while I do believe that the answers to all moral dilemmas are found within its pages, I don’t believe it is because morality/sin are its chief issue. Jesus is the central focus of the Bible.
Every book points ahead to Christ. Every book of the Old Testament is a Spirit-inspired wrapping—just as every book of the New Testament is a joyful declaration of the Gospel of Jesus. Jesus is the Good News. Jesus is the hope of the world. Jesus is the central figure of human history, the main idea of the Bible, and the Free Gift of God.
