“For a child will be born for us…” (Isaiah 9.6 CSB)
John 1.14 states, “And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.” Galatians 4.4-5 state, “But when the fullness of the time had come, God sent forth His Son, born of a woman, born under the law, to redeem those who were under the law, that we might receive the adoption as sons.” Finally, 1 Timothy 3.16 states, “Great is the mystery of godliness: God was manifested in the flesh.”
All of this NT revelation illuminates that which people in Isaiah’s day did not understand. A child will be born for us. He is a child born of a virgin woman, born under the Law in order to redeem those who were under the Law. You need redemption. That is, you must be set free from your sins. All of us have sinned. We all fall short of the glory of God. But a child was born for us. He lived a sinless life and offered Himself as a substitute for us. His sacrifice set us free. The Father made the Son, who knew no sin, to be sin for us. Why? He did so that we might become the righteousness of God in Him (see 2 Corinthians 5.21). Are you in Christ today?
