All the days of his separation he shall eat nothing that is produced by the grapevine, not even the seeds or the skins.
Nazirites had taken, among other vows, one that debarred them from the use of wine. In order that they might not violate the obligation, they were forbidden to drink the vinegar of wine or strong liquors; and to make the rule even clearer, they were not to touch the unfermented juice of grapes, nor even to eat the fruit either fresh or dried. In order to secure the integrity of the vow, they were not even allowed anything that had to do with the vine; they were, in fact, to avoid the appearance of evil.
Surely this is a lesson to the Lord’s separated ones, teaching them to come away from sin in every form, to avoid not merely its grosser shapes but even its spirit and likeness. Such strict walking is much despised in these days, but rest assured, dear reader, it is the safest and happiest path. He who yields a point or two to the world is in fearful peril; he who eats the grapes of Sodom will soon drink the wine of Gomorrah. A little crevice in the seawall in Holland lets in the sea, and the gap soon swells until a province is drowned.
Worldly conformity, in any degree, is a snare to the soul and makes it more and more liable to presumptuous sins. The Nazirite who drank grape juice could not be completely certain whether or not it had fermented and consequently could not be clear in heart that his vow was intact. In a similar way the yielding, vacillating Christian cannot have a clear conscience but is constantly aware of his double standard. Doubtful things we need not wonder about; they are wrong for us. Tempting things we must not play with, but run from them speedily. Better to be sneered at as a Puritan than to be despised as a hypocrite. Careful walking may involve much self-denial, but it has pleasures of its own that are more than a sufficient reward.
