4:2-6 No duties can be done aright, unless we persevere in fervent prayer, and watch therein with thanksgiving. The people are to pray particularly for their ministers. Believers are exhorted to right conduct towards unbelievers. Be careful in all converse with them, to do them good, and recommend religion by all fit means. Diligence in redeeming time, commends religion to the good opinion of others. Even what is only carelessness may cause a lasting prejudice against the truth. Let all discourse be discreet and seasonable, as becomes Christians. Though it be not always of grace, it must always be with grace. Though our discourse be of that which is common, yet it must be in a Christian manner. Grace is the salt which seasons our discourse, and keeps it from corrupting. It is not enough to answer what is asked, unless we answer aright also.
6. with grace—Greek, "IN grace" as its element (Col 3:16; Eph 4:29). Contrast the case of those "of the world" who "therefore speak of the world" (1Jo 4:5). Even the smallest leaf of the believer should be full of the sap of the Holy Spirit (Jer 17:7, 8). His conversation should be cheerful without levity, serious without gloom. Compare Lu 4:22; Joh 7:46, as to Jesus' speech.
seasoned with salt—that is, the savor of fresh and lively spiritual wisdom and earnestness, excluding all "corrupt communication," and also tasteless insipidity (Mt 5:13; Mr 9:50; Eph 4:29). Compare all the sacrifices seasoned with salt (Le 2:13). Not far from Colosse, in Phrygia, there was a salt lake, which gives to the image here the more appropriateness.
how ye ought to answer every man—(1Pe 3:15).
