Romans 14

5 One person regards a certain day above the others, while someone else considers every day alike. Each one should be fully convinced in his own mind. 6 He who observes a special day does so to the Lord; he who eats does so to the Lord, for he gives thanks to God; and he who abstains does so to the Lord and gives thanks to God.

Romans 13

8 Be indebted to no one, except to one another in love. For he who loves his neighbor has fulfilled the law. 9 The commandments “Do not commit adultery,” “Do not murder,” “Do not steal,” “Do not covet,” and any other commandments, are summed up in this one decree: “Love your neighbor as yourself.” 10 Love does no wrong to its neighbor. Therefore love is the fulfillment of the law.

Romans 8

5 Those who live according to the flesh set their minds on the things of the flesh; but those who live according to the Spirit set their minds on the things of the Spirit. 6 The mind of the flesh is death, but the mind of the Spirit is life and peace, 7 because the mind of the flesh is hostile to God: It does not submit to God’s law, nor can it do so. 8Those controlled by the flesh cannot please God.
