Isaiah 7-8 Ahaz, king of Judah, is given an opportunity to believe... to trust the Lord in the face of the threatening  armies of Israel and Aram.  He was given the choice of any sign he wanted to assure him of God's willingness to help.  But, instead Ahaz refused. He ignored the prophecies of Isaiah.  He reached out to Assyria and to Assyria's gods.  He desecrated the temple and brought about the destruction of his own country. ( I Kings 16)

" If you will not believe, you surely shall not last." (  Isaiah 7:9b)

Tozer writes about man's free will, the ability to choose... in his book The Knowledge of the Holy.   God, in His sovereignty, "decreed that man should be free to exercise moral choice, and man from the beginning has fulfilled that decree by making his choice between good and evil."   Tozer also goes on to remind us that God also has decreed that along with those choices are the consequences : " God has decreed that all who willingly commit themselves to His Son Jesus Christ in the obedience of faith shall receive life and become sons of God.  He has also decreed that all who love darkness and continue in rebellion against the high authority of heaven shall remain in a state of spiritual alienation and suffer eternal death at last. " 

Tozer conclues, " We must all choose whether we will obey the gospel or turn away in unbelief and reject its authority.  Our choice is our own, but the consequences of the choice have already been determined by the sovereign will of God, and from this there is no appeal. " 

Ahaz had every opportunity to make the right choice, but he refused.  He brought judgement upon himself and his country.

Father in Heaven,  Sovereign over Heaven and earth,  You have offered us life, eternal life through Jesus Christ, Your Son.  You have given us a choice and the ability to make a choice.  I am so thankful that You have given us eyes to see and ears to hear, hearts to receive Your Light, so that we might choose to willingly follow Jesus, laying our very lives down at Your feet.  Lord, nothing is impossible for You, and so I pray for those who have rebelled, those who have made the wrong choice... those whom I love dearly.. and I ask that You would open their eyes and ears, and that You would give them new hearts that will believe and follow Christ.   Oh Lord, may they choose right!
I ask this in the precious and powerful Name of Jesus.  Amen.
