He gives strength to the weary and increases the power of the weak. Even youths grow tired and weary, and young men stumble and fall.

— Isaiah 40:29-30

The sovereign Lord of the universe, who does not grow tired or weary, gives strength when we are weak and exhausted. We are subject to many weaknesses. Our strength quickly withers and fades. Our muscles and minds grow weary on the hard journeys of life. Fatigue is an unavoidable reality for us. Even the most dedicated, energetic people have passed through times of discouragement and weariness.From Moses to Elijah and from David to Hezekiah, the Lord’s chosen prophets and kings felt weakened at times (see Exodus 3-16; 1 Samuel 19-24; 1 Kings 19; 2 Kings 18-20). We can often feel the same way.But God is the source of our strength. God is our refuge and fortress. The apostle Paul agrees: “I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me” (2 Corinthians 12:9).God is our sustainer, and he renews our strength when we stumble and fall. He forgives our sins and heals our diseases. God keeps us on our feet in the struggles of life. He fights our battles and gives us victory. The Lord gives us our life, and he supplies us the power to live. Only in him can we move forward, despite our weaknesses. We can trust in him.

Lord, in our weakness we ask that you renew our strength. Lift us when we are weary, uphold us in every challenge and hardship, and fill us with your sustaining power so that we may find strength and rest in you. Amen.
