He gives strength to the weary and increases power to the weak.
(Isaiah 40:29 NIV)
When you are tired, washed up and done in, where do you go to get recharged? If you are a believer, your choice should be to turn to God and His word. He knows you get dirty in the world every day.
He knows you get depleted of time and energy. It is when you acknowledge that you need Him to empower you is when things change. When you read His word and spend time alone with Him, it brings peace and rest. You begin to see things as He sees them and you no longer allow the stresses of the world to weigh you down.
Be Encouraged! The world can weigh us down but when we turn our eyes on Jesus all else seems insignificant.
