Matthew Henry Commentary Proverbs 19:16

"He that keepeth the commandment keepeth his soul; [But] he that is careless of his ways shall die." — Proverbs 19:16 (ASV)

If we keep God's word, God's word will keep us from everything really hurtful. We abuse the doctrine of free grace if we think that it removes the necessity and advantage of obedience. Those who live carelessly must die. This truth is clearly taught in words sufficient to alarm the most hardened sinner.
