In this bad situation for Judah, with a godless king and enemies barking at his heels, God asks Ahaz if he is going to ask for a sign from God about what is going to happen. “Ahaz said, I will not ask, neither will I tempt the Lord” (7:12). The “house or David”, referring to Judah, was so callous in their disrespect of God that Isaiah says to them, “Is it too little for you to weary men, that you weary my God also?” They would not even speak to God in prayer. God is going to give them a sign anyway, one that speaks directly to the evil Ahaz had done with his own son. “Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel” (7:14). God will have HIS Son appear on earth on His terms.
This is a sign that defies human understanding! A “virgin shall conceive and bear a son”! It had never happened before in history and will never be repeated. It is a divine act proving that God will see that His truth prevails and His purpose succeeds no matter what anyone says or does, and He will do it in a way that cannot be denied. The question is; are we ready to receive God’s Son and let Him reign without any rival?
