Proverbs 21
"To do righteousness and justice is desired by the Lord rather than sacrifice" (v3). This was the theme of the prophets, who reminded all Israel that sacrifices were worthless without love and obedience. The proverbs warn against "haughty eyes and a proud heart" (v4), and offering huge, showy sacrifices may flow from this kind of arrogance (v27). The hidden, quiet virtues of kindness, private purity, and self-control reflect a heart which is truly devoted to God.
"Offer the sacrifices of righteousness, and trust in the Lord" (Ps 4:5). Sacrifices win the approval of people, but daily obedience demonstrates our love.
