The prophet Isaiah was called by God and sent to the nation of Judah with a dual message – one of judgment and mercy. Judgement would befall the nation if they did not turn from sin, idolatry, and injustice. But grace and mercy would be extended if they had contrite hearts of humility, repentance, and justice. In Isaiah chapter one below we read that God was not impressed by ritualistic worship. He desires instead a contrite heart.
(Isaiah 1:11-20) 11 “The multitude of your sacrifices— what are they to me?” says the Lord. “I have more than enough of burnt offerings, of rams and the fat of fattened animals; I have no pleasure in the blood of bulls and lambs and goats. 12 When you come to appear before me, who has asked this of you this trampling of my courts?
13 Stop bringing meaningless offerings! Your incense is detestable to me. New Moons, Sabbaths and convocations—I cannot bear your worthless assemblies. 14 Your New Moon feasts and your appointed festivals I hate with all my being. They have become a burden to me; I am weary of bearing them. 15 When you spread out your hands in prayer, I hide my eyes from you; even when you offer many prayers, I am not listening. Your hands are full of blood!
16 Wash and make yourselves clean. Take your evil deeds out of my sight; stop doing wrong. 17 Learn to do right; seek justice. Defend the oppressed. Take up the cause of the fatherless; plead the case of the widow. 18 “Come now, let us settle the matter,” says the Lord. “Though your sins are like scarlet, they shall be as white as snow; though they are red as crimson, they shall be like wool. 19 If you are willing and obedient, you will eat the good things of the land; 20 but if you resist and rebel, you will be devoured by the sword.” For the mouth of the Lord has spoken.
