Romans 13:14 - Matthew Poole's English Annotations on the Holy Bible

Put ye on the Lord Jesus Christ; he exhorted, Romans 13:12, to put on the armour of light; now, to put on Jesus Christ. This is necessary, for though grace may help to defend, yet it is Christ and his righteousness only that can cover us (as a garment doth our nakedness) in the sight of God. To put on Christ, is to receive him and rest upon him by faith; as also to profess and imitate him. You have the same phrase, Galatians 3:27. Make not provision for the flesh, to fulfil the lusts thereof: by flesh, here, some understand the corrupt nature; others, the body. When he says, make not provision for the flesh, he doth not mean, that they should not provide things necessary for the body; this is allowed, Ephesians 5:29 1 Timothy 5:23; we are no where commanded to neglect or macerate our bodies; but he means, that we should not gratify it in its sinful lusts or lustings: see 1 Corinthians 11:27. Sustain it we may, but pamper it we may not: we must not care, cater, or make projects for the flesh, to fulfil its inordinacics and cravings.
