My Well-beloved and his vineyard on a fruitful hill brought forth wild grapes. The sour grapes of sin and rebellion came forth. But the sweet grapes, the wholesome taste of fruitful righteousness came not forth. Thus, the Lord of the vineyard had done all to bring it forth in sweet righteousness. While the covenant in Isaiah day was from the Sinai covenant and the Abrahamic covenant; there are many things that speak to us.
