What does the Bible say about mercy and sacrifice?

In Matthew 12:7, Jesus quotes Hosea 6:6, saying, 'I will have mercy, and not sacrifice.' This statement underscores that God values a heart of mercy and compassion over mere adherence to religious rituals. The Pharisees of Jesus' time were caught up in the seriousness of the law to the detriment of understanding God's merciful character. They believed their sacrifices and law-keeping earned them favor with God, missing the core message that true mercy comes from God and is shown through acts of kindness and love, reflecting His character.
