50. From these considerations it may be seen what spiritual faith is, and what the faith is which is not spiritual. Faith is spiritual with those who do not commit sins; for those who [do not] commit sins do good not from themselves but from the Lord, as may be seen above Nos. 18-21; and by faith they become spiritual. Faith with them is the truth (veritas). This the Lord thus teaches in John:
This is the judgment, that light is come into the world, but men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God. John iii 19-21.
