How do we know God desires mercy, not sacrifice?

This principle is illustrated through the example of King Saul in 1 Samuel 15, where God rebukes Saul for thinking that sacrifice could replace obedience. The text reveals that true obedience comes from trusting in God’s mercy through Christ, rather than through outward acts of righteousness. Jesus echoed this when He stated, 'I desire mercy, not sacrifice.' This shows that what God seeks is a heart willing to confess and rely on His grace rather than efforts to earn favor through ritualistic practices.
