“Do you not know?
Have you not heard?
The Lord is an eternal God,
the Creator of the whole earth.
He does not get tired or weary;
there is no limit to his wisdom.
He gives strength to those who are tired;
to the ones who lack power, he gives renewed energy.”
Israel told herself that God was not concerned with her problems, v. 27. Repeatedly, Isaiah told the people that the problem was not with God, but with her sins, Isa 59.1-8.
“Believers cannot win the battle by themselves. They need the power of God, Ephesians 3:16; 6:10. His power becomes our strength when we trust in Him, II Corinthians 12:9. Faith is like an extension cord. When plugged into God, divine strength flows into human beings. The key is being plugged in, Ephesians 1:18-21; 3:20; Colossians 1:29. But, when we are firmly jointed to Him, we become more than conquerors through Him who loved us, Romans 8:35,37-39.” —Ed Mathews, “Plow New Ground”
