What was Israel promised if they were obedient?
Israel was promised that if they were obedient, they could be a kingdom of priests. This is linked to Israel being a light, with Gentiles coming to their light, and the Redeemer coming to Zion to those who turn from transgression.
Les explains that Israel was promised that if they would be obedient, they could be a kingdom of priests. He connects this to Isaiah 60, where Israel is told to arise and shine because their light has come and the glory of the Lord is risen upon them. The darkness shall cover the earth, but the Lord will arise upon Israel, and Gentiles shall come to their light. Les also notes the Redeemer shall come to Zion to those who turn from transgression, and God's covenant and Spirit will not depart from Israel's mouth or their seed forever.
