Isaiah 40:3, 28-29

This is the voice of one who calls out: “Prepare in the desert the way for the LORD. Make a straight road in the dry lands for our God.

Surely you know. Surely you have heard. The LORD is the God who lives forever, who created all the world. He does not become tired or need to rest. No one can understand how great his wisdom is. He gives strength to those who are tired and more power to those who are weak.
