What does the Bible say about living by the Spirit?

In Romans 8:12-13, Paul emphasizes that we are not debtors to the flesh to live according to the flesh. He clearly states that if we live according to the flesh, we shall die, but if we, through the Spirit, put to death the deeds of the body, we shall live. This establishes a vital truth in the Christian faith that our life and sanctification come by the Spirit, not by our own works or efforts. Living by the Spirit involves depending on Christ, who is our life, and acknowledging that it is through Him that we have been given new life and the ability to walk in holiness.
