 All scripture is God breathed. All scripture is useful in teaching me about how to walk with my God. Even when you read in the New Testament, God says in Galatians chapter 6, verse 7 through 8, Do not be deceived. God cannot be mocked. A man reaps what he sows. Whoever sows to please that flesh, from that flesh will reap destruction. Whoever sows to please the Spirit, from the Spirit will reap eternal life.
