Our Scripture reading today is 2 Corinthians 12:7-10.
Verse 10, "Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong."
The Apostle Paul recognized something that the sooner we recognize the better.  He recognized he had numerous limitations.  He was not able to do everything required of him.  The great Apostle Paul needed help.  This recognition of insufficiency actually led to his being stronger in the power of the Lord.  He concludes verse 10 with the statement, "Then am I strong."  When I know that I am weak and limited, it opens up the door to strength beyond me.
It's Tuesday morning and you are already tired.  Possibly there is a burden you are carrying that is bringing you down.  The work load is too heavy.  You are experiencing some physical issues.  I know this verse provides us with the vision of how to have victory each and every day.  The sooner we recognize our inabilities, we will claim His ability.  It is ok to admit we cannot do something as long as we claim the promise of Philippians 4:13, "I can do all things through Christ which strengtheneth me."  Only His power makes us effective for Him and will produce fruit with eternal value.
