Why did all the sons of God shout for joy, and the morning stars sing as one, when the corner stone was laid?

Two ways met at this corner; Law & Grace. The Corner Stone upon whom both, the Law & Grace, was founded is Jesus Christ for their is no other foundation on which to build according to the Word. Isa 40:1-3, tells us why such Joy; Her warfare is accomplishe, her iniquity is pardoned, she has received double at the Lord's hand for ALL her sins. Yes, joy beyond measure. Thank ynu Lord Jesus!
