The phrase ’good works’ is a common one in society, where it means being kind to the unfortunate or giving to charity. These acts are helpful, but they can be done by anyone; for example, an immoral person can do them. Paul does not have such an attitude in mind, for the good works to which he refers are done only by Christians, and that because of God’s grace.
Good works, in the Pauline sense, are both the consequence and the evidence of conversion. From God’s point of view or from a theological point of view, they are the inevitable consequence of conversion. From the point of view of other people they are the evidence that God has renewed a particular person.
The key to a proper walk with God is found in our attitudes as well as in our actions. While the picture of ‘walking’ indicates continuation in the path, we must see what it is that gives us the spiritual energy to walk. We need to feed our souls, breathe a pure atmosphere and take regular health checks. We feed on Christ, we spend time in prayer and we engage in self examination. Then all kinds of 'good works' will follow.
