If we treat the Bible as a complete catalog of "do's" and "don'ts", then we can almost always find a way to justify whatever we want to justify. From slavery to genocide, you can find a scripture to "prove" just about anything you want in the Bible. But if we recognize that Jesus is the Living Word with whom we must engage, then we are engaging with the Logos of Life - God's Wisdom of how to live. To believe in Jesus is to believe that he is what God has to say. If you'll believe in the Logos of Life (Christ), your soul will be healed and you will find life.
