I always understood his viewpoint to be that good works result from our faith.
Romans 12:9-21 New International Version (NIV)
Love in Action
9 Love must be sincere. Hate what is evil; cling to what is good.
10 Be devoted to one another in love. Honor one another above yourselves.
11 Never be lacking in zeal, but keep your spiritual fervor, serving the Lord.
12 Be joyful in hope, patient in affliction, faithful in prayer.
13 Share with the Lord’s people who are in need. Practice hospitality.
14 Bless those who persecute you; bless and do not curse.
15 Rejoice with those who rejoice; mourn with those who mourn.
16 Live in harmony with one another. Do not be proud, but be willing to associate with people of low position.3 Do not be conceited.
17 Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everyone.
18 If it is possible, as far as it depends on you, live at peace with everyone.
19 Do not take revenge, my dear friends, but leave room for God’s wrath, for it is written: “It is mine to avenge; I will repay,”4 says the Lord.
20 On the contrary: “If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this, you will heap burning coals on his head.”5
21 Do not be overcome by evil, but overcome evil with good.
Romans 8:5-8:
5 Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires.
6 The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace.
7 The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so.
8 Those who are in the realm of the flesh cannot please God.
