15 I will make waste mountains and hills, drying up all their plants; and I will make rivers dry, and pools dry land. 16 And I will take the blind by a way of which they had no knowledge, guiding them by roads strange to them: I will make the dark places light before them, and the rough places level. These things will I do and will not give them up. 17 They will be turned back and be greatly shamed who put their hope in pictured images, who say to metal images, You are our gods.

Matthew Henry's Commentary on Isaiah 42:15-17

Commentary on Isaiah 42:13-17

(Read Isaiah 42:13-17)

The Lord will appear in his power and glory. He shall cry, in the preaching of his word. He shall cry aloud in the gospel woes, which must be preached with gospel blessings, to awaken a sleeping world. He shall conquer by the power of his Spirit. And those that contradict and blaspheme his gospel, he shall put to silence and shame; and that which hinders its progress shall be taken out of the way. To those who by nature were blind, God will show the way to life and happiness by Jesus Christ. They are weak in knowledge, but He will make darkness light. They are weak in duty, but their way shall be plain. Those whom God brings into the right way, he will guide in it. This passage is a prophecy, and is also applicable to every believer; for the Lord will never leave nor forsake them.
