When to Say No to the World
The caution or exhortation itself, not to mingle with unbelievers, not to be unequally yoked with them, v. 14. Either,
1. In stated relations. It is wrong for good people to join in affinity with the wicked and profane; these will draw different ways, and that will be galling and grievous. Those relations that are our choice must be chosen by rule; and it is good for those who are themselves the children of God to join with those who are so likewise; for there is more danger that the bad will damage the good than hope that the good will benefit the bad.
2. In common conversation. We should not yoke ourselves in friendship and acquaintance with wicked men and unbelievers. Though we cannot wholly avoid seeing, and hearing, and being with such, yet we should never choose them for our bosom-friends.
3. Much less should we join in religious communion with them; we must not join with them in their idolatrous services, nor concur with them in their false worship, nor any abominations; we must not confound together the table of the Lord and the table of devils, the house of God and the house of Rimmon.
Who can touch pitch, and not be defiled by it? We must take care not to defile ourselves by converse with those who defile themselves with sin
