(5) Walk in wisdom . . . redeeming the time.--In the parallel passage (Ephesians 5:15) we have "walk strictly, not as fools, but as wise," and the limitation "towards them that are without" is omitted, although it is added that "the days are evil." The context, as will be seen by reference, is different, and the idea also somewhat different. There the "strictness" and "wisdom" are to guard against excess or recklessness within; here the "wisdom" is to watch against external dangers and make full use of external opportunities.

Verse 5. - Walk in wisdom towards those without (Ephesians 5:15-17; 1 Thessalonians 4:12; 1 Thessalonians 5:15; 1 Corinthians 10:32; 2 Corinthians 4:2; Titus 2:8; 1 Peter 2:12, 15; 1 Peter 3:16; Matthew 10:16). (On "wisdom," see Colossians 1:9, note; Colossians 1:28; 2:3; 3:16; this was a chief need of the Colossian Church.) "Those without," as opposed to Christians - "those within the pale;" a Jewish mode of expression (Lightfoot): comp. 1 Thessalonians 4:12; 1 Corinthians 5:12, 13; 1 Timothy 3:7. From a different point of view, they are designated" the rest" in Ephesians 2:3; 1 Thessalonians 4:13; 1 Thessalonians 5:6. This injunction appears in a different form and position in Ephesians. Standing at the close of the writer's exhortations, and followed up by the direction of the next verse, it is more pointed and emphatic here. Buying up each (literally, the) opportunity (Ephesians 5:16; 1 Corinthians 7:29; Galatians 6:10; John 11:9, 10; Luke 13:32; Ecclesiastes 3:1-8). In Ephesians 5:16 the reason is added, "because the days are evil." In Daniel 2:8 (LXX) the verb ἐξαγοράζω ("to buy out" or "up," a word of the market) has precisely this sense and connection, and the idiom occurs in classical writers. The verb is middle in voice: "buying up for yourselves," "for your own advantage." In Galatians 3:13 the compound verb is somewhat differently used. The opportunity is the fit time for each step of a well-conducted walk, the precise juncture of circumstances which must be seized at once or it is gone. This wary promptitude is always needful in dealing with men of the world, both to avoid harm from them and in seeking to do them good. The latter thought, it may be, connects this verse and the next.

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.Walk in wisdom,.... Or wisely, circumspectly, not as fools, but as wise men; See Gill on Ephesians 5:15.

Towards them that are without; so the Jews used to call the Gentiles, all that were out of their own land, that were not of their nation or religion, who were aliens from them, and strangers to their privileges; and sometimes the unbelieving. Jews bear the same character, see Mark 4:11. Here it may design such who were not members of this church; so the distinction of those that are without, and such as are within, is used by the apostle in 1 Corinthians 5:12. A church is an house or family, and such as belong to it are called the household of faith, and those that do not are they that are, without; it is as a city, and, those that are of it are fellow citizens with the saints, but others are strangers and foreigners; it is a garden enclosed, they that are planted in it are those that are within, and such as lie in the wide open field of the world are those that are without: but inasmuch as there are some who are not members of churches, and yet have the grace of God, this phrase may chiefly regard all unregenerate men, profane sinners, such as have not faith in Christ, nor hope in God, who are entirely destitute of the grace of God. Now it becomes saints to walk wisely towards them; all communication with them is not cut off, or correspondence and conversation with them forbidden; the saints indeed are not to have their conversation among them as in times past; they are to have no fellowship with them in immoral actions, and superstitious practices; but they may be concerned with them in things civil, with respect to trade and commerce, and the common business of life; on these accounts they may keep company with them; otherwise, as the apostle elsewhere says, they must needs go out of the world. But then it is incumbent upon them to behave wisely towards them, with the simplicity of the dove to join the wisdom of the serpent; they should walk inoffensively towards them, and do nothing to provoke them, to injure and persecute them, but take all prudent methods to gain their affections, escape their resentment and wrath, and obtain their liberty of worshipping God without disturbance; they should give to all their due, tribute, custom, fear, and honour, to whom they are due, and owe no man anything but love; they should submit to every ordinance of men and be subject to the higher powers, not only to escape wrath, but for conscience sake, and should give to Caesar the things that are Caesar's; they should pray for kings, and all in authority; for the prosperity of the nation, city, and place where they are, for their carnal relations and neighbours, and even their very entities, and do them all the good, both for soul and body, that lies in their power, and as they have opportunity; and by so doing, they will heap up coals of fire on their heads. Such a prudent walk, and wise conduct, is necessary on account of the Gospel, that the public ministration of it may be continued, that it may spread and get ground, and that it may not be reproached and blasphemed; and on the account of them that are without, that they may not have any stumblingblocks laid in their way, and they be hardened in their impiety and irreligion, and be more set against the truths of the Gospel; and also on account of believers themselves, who ought so to converse with the men of the world, that they are not partakers with them in their sins, and have their manners corrupted by them, or the vital heat of religion damped, and they become dead, lifeless, lukewarm, and indifferent to divine things, which is often the case through an indiscreet and imprudent walk with such men: the apostle adds,

redeeming the time; as an instance of prudent walking towards them that are without; See Gill on Ephesians 5:16.
