What does Isaiah 8:17 mean?
Isaiah makes a declaration of his continued faith in the Lord. This is despite the Lord's choice to stop blessing Israel and Judah in this season of disobedience. Instead of looking for a new source of salvation, Isaiah will continue to wait for God to keep His promises to those who are faithful to Him. His hope in the Lord is not dependent on the situation surrounding him.The prophet has a deep understanding of why the Lord's judgment is coming on Judah: the unfaithfulness of the people (Isaiah 8:6). He refuses to abandon the Lord and instead insists that he will continue to hope in the One in whom he has put his faith.
In Hebrews 2:13, the writer quotes Jesus as saying these words from Isaiah, "I will put my trust in him." Jesus experienced the judgment of God on human sinfulness—not through the invading Assyrians but on the Roman cross. Jesus also experienced God hiding His face in that moment (Matthew 27:46). The judgement of God that Jesus experienced was not due to unfaithfulness, it was His choice to go to that cross (2 Corinthians 5:21). Even though no fault of His own, Jesus refused to turn from His father in that time of darkness. Isaiah was not a perfect man, but he chose to hold his hope in the Lord.
