If only man could even begin to smell how foul to the nostrils of God sin is, how repugnant to the eye of God the child who transgresses His law, our hearts would indeed be torn asunder and we would fall before God prostrate of a poor spirit and mourning for our broken condition. Jude points to the gross sinner as being a spot in our love feasts, and speaks of the turmoil that surrounds them. So it is with unconfessed sin in the life of the believer. God's love is everlasting, so is His chastisement certain for those who sin against Him. Meditate upon these things, whereby the hedge of God's love remains high and strong.
Sin opens the hedge exposing the workers in the vineyards to the dangers of the beasts without.
So much so, except for the grace of God, even the very elect would be lost.
