Ephesians 6:10 - "be strong in the Lord, and in the power of his might." - The arm of flesh will fail you. No matter how strong it may seem to be. This is why we are not to trust in the flesh but the Lord. We can lean on the Lord and His strength. After all He is ALLPOWERFUL. So, whatever battle you face you can trust that God can handle the situation. He is strong enough to help you no matter how big the problem.
