There is a common thread in today’s Readings. Each reading highlights a various change wrought in us by the Lord. Ezekiel alluded to Baptism, that by it God separates us from the world, gives us a new heart, and gives us His Holy Spirit. Isaiah called us to a Christian life, to doing good works that are pleasing in God’s eyes. However, he reminded us that when we fail, God forgives us. Finally, in the Gospel Jesus healed the man born blind and was hated for it. But for the man who was healed, the Word of Jesus created faith in him and brought him from spiritual darkness into the light.
Why does the Pastor preach? Scripture explains that the role of preaching the Word of God is how saving faith is created: “How then will they call on Him in whom they have not believed? And how are they to believe in Him of whom they have never heard? And how are they to hear without someone preaching? And how are they to preach unless they are sent? As it is written, ‘How beautiful are the feet of those who preach the good news!’ … So faith comes from hearing, and hearing through the Word of Christ” (Romans 10:14-17). The Augsburg Confession, seeing this connection between the Preaching Office and saving faith, summarizes Scripture on the Office of the Holy Ministry in this way: “To obtain [saving, justifying] faith, God instituted the Office of Preaching, giving the Gospel and the Sacraments. Through these, as through means, He gives the Holy Spirit who produces faith, where and when He wills, in those who hear the Gospel. It teaches that we have a gracious God, not through our merit but through Christ’s merit, when we so believe” (AC V 1-3). The whole reason the Pastor preaches is so saving faith can be created, so we know that “we have a gracious God” who loves us and has saved us from our sin by the death and resurrection of Jesus Christ.
