До колосян 4:5

(See on Eph 5:15-16.) in wisdom--practical Christian prudence. them . . . without--Those not in the Christian brotherhood (Co1 5:12; Th1 4:12). The brethren, through love, will make allowances for an indiscreet act or word of a brother; the world will make none. Therefore be the more on your guard in your intercourse with the latter, lest you be a stumbling-block to their conversion. redeeming the time--The Greek expresses, buying up for yourselves, and buying off from worldly vanities the opportunity, whenever it is afforded you, of good to yourselves and others.

Walk circumspectly, redeeming the time, because the days are evil, that is, dangerous, or times of trouble and suffering. And towards others, or those who are within as well as those who are without, "Let your speech be always with grace, Col 4:6. Let all your discourse be as becomes Christians, suitable to your profession - savoury, discreet, seasonable." Though it be not always of grace, it must be always with grace; and, though the matter of our discourse be that which is common, yet there must be an air of piety upon it and it must be in a Christian manner seasoned with salt. Grace is the salt which seasons our discourse, makes it savoury, and keeps it from corrupting. That you may know how to answer every man. One answer is proper for one man, and another f…
