After the promises made in Isaiah 44:1-5, the Lord Yahweh speaks once more to remind Israel of his uniqueness, that he is the one and only God, and to reassure them there is no one else who can be their sure foundation. Rather than be like the nations, who seek deliverance from idols, God’s people were to be witnesses of his redeeming love and renewing grace. In this sermon, pastor Matt wraps up this section of Isaiah, emphasizing how God’s purpose in the redemption of his people is the praise of his name. The goal of his gospel is a people, renewed by his Spirit and reassured by his grace, who worship him and bear witness to the truth that there is no rock like our God.
