2 Corinthians 3. Believers are Christ’s Epistle with the the spirit of the living God living within them.“The letter killeth, but the spirit giveth life” , that is the glory of the New Covenant, and “where the spirit of the Lord is, there is liberty”
Isaiah 9. A must read chapter of Isaiah. It speaks of “The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined.” Then it states: “For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.” It speaks of Christ, the coming Messiah, both his humanity (a child) and his deity (son of God).
