True worship requires the right sacrifice, as illustrated by Abel's offering, which involved blood and symbolized the seriousness of sin and the need for atonement. In contrast, Cain's offering, though beautiful, was rejected because it was a product of his own hard work and pride. This teaches us that worship must be based on God's instructions and not our own efforts. Our sacrifices to God should reflect humility and obedience, acknowledging our need for His grace and forgiveness.
"For I desire steadfast love and not sacrifice, the knowledge of God rather than burnt offerings." (Hosea 6:6, ESV)
Reflections: Reflect on your own acts of worship. Are they based on God's instructions or your own efforts? How can you ensure that your worship is pleasing to God and not driven by pride or self-reliance?
