In the Old Testament, two goats were offered during the Day of Atonement (Leviticus 16). The sinner was commanded by the Lord through Moses that he should bring his best and blemishless goat from his herd to give it as an offering for his sins. The sinner would identify with the ‘sacrificial goat’, whose blood was for the remission of his sins. In the New Testament, we identify with Jesus the Lamb of God for the remission of our sins!
God sent Jonah to Nineveh, the capital of Assyria to pronounce a message of judgement over it. After he preached the message reluctantly, God forgave the people of Nineveh and never destroyed their city because they repented before Him. Apart from the fact that God made him look like a false prophet, Jonah detested the idea of a ‘God of unlimited grace’. Why should grace be extended to the Assyrians, who were the worst enemies of Israel? He preferred a God who gave people what they deserved.
Luke 7:36-50
