For indeed, grace is the key to it all. It is not our lavish good deeds that procure salvation, but God's lavish love and mercy. That is why the poor are as acceptable before God as the rich. It is the generosity of God, the freeness of his salvation, that lays the foundation for the society of justice for all. Even in the seemingly boring rules and regulations of tabernacle rituals, we see that God cares about the poor, that his laws make provision for the disadvantaged. God's concern for justice permeated every part of Israel's life. It should also permeate our lives.
