Ephesians 4:23

23 And be renewed in the spirit of your mind;

Ver. 23. In the spirit of your mind ] That is, in the most inward and subtle parts of the soul, the bosom and bottom, the vis vivifica, and very quintessence of it. This he calls elsewhere the wisdom of the flesh, Romans 8:7 , that carnal reason, that, like an old beldam, is the mother and nurse of those fleshly lusts that fight against the soul.
