What does the Bible say about God giving strength to the weary?

In Isaiah 40:29, God promises that He gives power to the faint and increases strength to those who have no might. This reflects the sovereign grace of God, assuring His people that even in their weakness, He provides the necessary strength to endure life's challenges. The assurance that God does not grow weary or faint serves as a comfort to believers who often feel overwhelmed by their circumstances. As believers, we are reminded to wait upon the Lord, relying on His infinite power rather than our own limited abilities.
