How do we know that mercy is more important than sacrifice in the context of the Sabbath?

Jesus' teachings in Matthew 12:7, quoting the Old Testament, emphasize that God desires mercy, not sacrifices. The Pharisees were criticized for their rigid interpretations of the law, which eclipsed the fundamental principles of compassion and kindness. By citing the examples of David and the priests, Christ demonstrated that acts of mercy and fulfilling human needs take precedence over ritualistic adherence to the law. This principle is foundational in understanding the nature of God, who values human compassion and mercy over mere ceremonial compliance. Through Christ, we see that the fulfillment of the law is rooted in love and mercy, opening a way for genuine worship and service to God.
