Isaiah 40:31

But those who wait for the Lord (who expect, look for, and hope in Him) will gain new strength and renew their power; they will lift up their wings (and rise up close to God) like eagles (rising toward the sun); they will run and not become weary, they will walk and not grow tired.

We are starting a new year and have renewed hope in the Lord. When we wait on the Lord and expectantly hope in Him, the Lord will renew our strength and power. We cannot increase our endurance on our own, but the Lord is able to lift us up. We can go forward with God guiding us and building us up.
