I can't speak for you, but I confess that there are times I want to throw in the towel, check out, run through the woods!  I get weary with doing "stuff" and realizing I didn't do something I should have or I messed up on something else.  Can I get a witness?

The truth is that God wants us to keep persevering.  Here is the way the Lord says it to us, And let us not be weary in well doing: for in due season we shall reap, if we faint not.  Galatians 6:9

Do we really catch it?  It's the devil who wants us to quit!  As long as we do like the Apostle Paul and "press toward the mark of the prize of the high calling in Christ," in other words even though we realize we aren't perfect, we don't always do it right, and we get tired - if we do not quit, we receive the reward.  I want to hear Jesus say, "Well done my good and faithful servant."  So what can I do?  Just not quit...
