What does Isaiah 1:12 mean?
The idea in this verse seems to be that God considered the Israelites to be trespassing: stomping around in His sacred presence without reason. They came to Him with sinful hearts merely to carry out religious ritual with no intention of changing direction.The Lord was the one who required them to come and make their offerings and bring their sacrifices. He is revealing here His intention for the sacrificial system: to represent the humility and repentance of God's people for their sin. Instead, Israel was using sacrifices and ritual as a substitute for making right choices and working to abandon their sinful practices. Their hearts remain sinful even in the act of worshiping the Lord.
