Colossians 4:6

With grace; such as grace dictates; speak what is seasonable, pertinent, instructive, useful.

Seasoned with salt; not insipid and profitless, but, like well-seasoned food, wholesome and promotive of the edification of all who hear.

Know how-to answer; in order to give just views and make right impressions. The apostle probably has special reference to the questions of "those without," the answers to which would require much circumspection and heavenly wisdom. Much, very much depends upon the proper use of the tongue. It may be "a world of iniquity" or a fountain of life. Every person therefore, especially every Christian, should pray and strive for wisdom and grace rightly to use his tongue; knowing that by his words he will be justified or condemned; that if any man offend not in word, the same is a perfect man; and that words fitly spoken are like apples of gold in a net-work of silver. Proverbs 18:21; Proverbs 25:11; Matthew 12:37; James 3:2-18.
