Sermons on Isaiah
Zion was in darkness due to her sins, but now, as a result of the salvation worked through the Messiah, light arises over her. The coming of Christ leads to all nations coming and serving Zion, bringing their tribute, as she is gloriously transformed in the new creation. The gifts that are brought are fulfilled when the light of a star arises over Christ and the Magi bring their gifts of tribute to him at his birth.
God looks and sees that there is no one righteous, no one to deliver His people, and so He Himself acts as deliverer, putting on the armor of God. He sends a Savior to Zion who banishes ungodliness from her by the Word and Spirit. Ultimately, the prophets see only the work of the Messiah as the true hope for the people of God in their sin.
In Isaiah 59:1-15 Isaiah returns to the theme of the sins of God’s people. Their sin causes a separation from God and is described as being in darkness. Sin and the judgment that follows is related to the darkness of non-creation. The light of salvation bursting through the darkness signals a new creation.
Having discussed true fasting, Isaiah moves on to describe faithful Sabbath keeping. God has set apart one day in seven for the worship of His name. This is not a day for the pursuit of our own pleasure but a day consecrated to God. From the beginning of the world until the coming of Christ, this day was Saturday, but from his resurrection all the way to his return, the day is Sunday, the Lord’s Day, the day when the…
In Isaiah 58:1-12 Isaiah addresses the people’s hypocrisy in fasting. They believed that their fasting was pleasing to Him, and yet God actually despised it. Fasting without love and compassion for others is not pleasing to God. Our worship is merely hypocrisy if it is done in hatred of our brothers and sisters.
Isaiah contrasts the house of the prostitute with the house that is faithful to Him. Those who trust in God will inherit the mountain of God and dwell with Him forever. They come to this inheritance being led by God Himself on the highway prepared for this very purpose.
Having described the wickedness of Israel’s leaders, Isaiah moves on to describe the sins of the people. The people of God have been faithless in their idolatry, which the prophets everywhere take to be adultery against God. To be faithful to God, we must worship Him according to His Word.
Isaiah says that the faithful outsider will be included in the kingdom of God (56:1-8), but the faithless insider will be excluded. Here the focus is on the leadership of the people of God. Poor leadership causes great harm to the church.
The gospel often comes to those who are overlooked in society. Isaiah, prophesying of the days of Christ, speaks of the inclusion of the eunuch and the foreigner in the kingdom of God. This is fulfilled pointedly with the conversion of the Ethiopian eunuch in Acts 8.
What is the primary motivation for evangelism? The glory of God. The reason every Christian ought to be committed to evangelism is because God is not worshiped as he ought to be. If you love God, then this means you must be committed to worshiping him. If you are committed to worshiping him, then you ought also to strive to see him worshiped by others.
Isaiah 7:1-16 contains the famous prophecy of the virgin giving birth to a son named “Immanuel” and is part of the larger “book of Immanuel” in chapters 7-12. What was the context of this prophecy? The people of Judah and the house of David faced terrible trials as enemies seemed to be surrounding them on every side. What hope did the prophets give the people? The coming of the Messiah. Though the troubles of life tempt us to take our eyes off of Christ, ultimately, he is the only hope we have.
