Here is, 1. The peril of a sinful way. There is not only a punishment at the end of it, but a snare in it. One sin is a temptation to another, and there are troubles which, as a snare, come suddenly upon evil men in the midst of their transgressions; nay, their transgression itself often involves them in vexations; their sin is their punishment, and they are holden in the cords of their own iniquity, Proverbs 5:22.
2. The pleasantness of the way of holiness. The snare that is in the transgression of evil men spoils all their mirth, but righteous men are kept from those snares, or delivered out of them; they walk at liberty, walk in safety, and therefore they sing and rejoice.
Those that make God their chief joy have him for their exceeding joy, and it is their own fault if they do not rejoice evermore. If there be any true joy on this side heaven, doubtless those have it whose conversation is in heaven.
