The Gospel in Isaiah

Isaiah 9:6-7 is a great prophecy of Christ. It shows HOW He came into the world, WHO He really is, WHY He came, and WHAT He accomplished--

“For unto us a child is born,”- This speaks of His holy, sinless humanity, conceived in the virgin’s womb by the Holy Spirit. Christ is the ‘seed of woman,’ (Genesis 3:15).
“unto us a son is given:” This speaks of His eternal deity. His godly nature was not created or born. He is the eternal Son of God, Alpha and Omega, having no beginning and no end. He is the great ‘I AM’ (John 8:58).
“and the government shall be upon His shoulder,”- This speaks of WHY He came. It was to fulfill ALL THE CONDITIONS and REQUIREMENTS of the salvation of God’s elect. This is the government of grace, and all grace is in Christ (John 1:17).
“and His name shall be called Wonderful, Counselor, The Mighty God, the Everlasting Father, the Prince of Peace.” This describes His Person in all the facets of His glory as the Redeemer and the Lord of His people (Colossians 1:19; 2:9; 2 Corinthians 4:6).
"Of the increase of His government and peace there shall be no end, upon the throne of David, and upon His kingdom,”- This describes the ASSURED FRUIT AND RESULT OF HIS FINISHED WORK, for “He SHALL save His people from their sins,” (Matthew 1:21). The ‘throne of David’ is the messianic throne of Christ our Redeemer. ‘His kingdom’ is His church whom He redeemed by His own blood.
"to order it, and to establish it with judgment and with justice from henceforth even for ever." THIS DESCRIBES HIS FINISHED WORK ON THE CROSS. God is both just and justifier as the sins of God’s elect were imputed to Christ and His righteousness was imputed to them (Romans 3:24-26; 2 Corinthians 5:21).
“The zeal of the LORD of hosts will perform this.” This shows how ALL of salvation is of the Lord, by His power, and for His glory.
