Thomas Aquinas, on Eph 5:16

“But as wise: redeeming the time, because the days are evil.”

“He explains the necessity of this precaution when he says redeeming the time, which can be interpreted in two ways. On certain occasions a man redeems his property by offering a gift or something else for it; for instance, someone is said to compensate for a grievance he caused by offering a gift or money, or by renouncing something which is rightfully his. In this sense he would be saying: The whole of time is now a time of deception, hence you should be redeeming the time, because the days are evil. At the time Adam sinned, and from then on, snares have always been set to thrust men into sin. It was not that way in the state of innocence when it was unnecessary for a man to abstain from anything which was licit, since there was nothing in his will driving him to sin. But now we have to redeem the time, because the days are evil; we must avoid the depravity of the days, and "beware beforehand of the evil day," as Ecclesiastes 7 (15) expresses it. To do this we must renounce even certain things which are lawful: "All things are lawful for me; but all things do not edify" (1 Cor. 10:23). In this way a person is said to redeem a grievance he caused since he permits something that is rightfully his to be forfeited. There is another interpretation of redeeming the time. For it sometimes happens that a person lives a great part of his life in sin, and this is time lost. But how is he to redeem it when man is incapable of paying his debts? I reply that he ought to devote himself to good works to an even greater degree than he had previously pursued sinful ones. "For the time past is sufficient to have fulfilled the will of the Gentiles, for them who have walked in riotousness, lusts, excesses of wine, revellings, banquetings, and unlawful worshipping of idols" (1 Pet. 4:3). The first interpretation, however, is better.”
