When weary...

28 Have you not known? Have you not heard?
The Lord is the everlasting God,
    the Creator of the ends of the earth.
He does not faint or grow weary;
    his understanding is unsearchable.
29 He gives power to the faint,
    and to him who has no might he increases strength.
30 Even youths shall faint and be weary,
    and young men shall fall exhausted;
31 but they who wait for the Lord shall renew their strength;
    they shall mount up with wings like eagles;
they shall run and not be weary;    they shall walk and not faint.
(Isaiah 40:28-31)
Life lately has made many of us more than a little weary.  It is predictable, understandable, and even promised: 
And let us not grow weary of doing good, for in due season we will reap, if we do not give up. (Galatians 6:9)
13 As for you, brothers, do not grow weary in doing good. 14 If anyone does not obey what we say in this letter, take note of that person, and have nothing to do with him, that he may be ashamed. (II Thessalonians 3)
3 Consider him who endured from sinners such hostility against himself, so that you may not grow weary or fainthearted. 4 In your struggle against sin you have not yet resisted to the point of shedding your blood. (Hebrews 12)
There are many reasons we may "grow weary": we don't seem to be getting anywhere; others seem to be messing up our lives, or at least are not doing anything to help matters; we keep feeling the pull of sin dragging us down.  All of these things weigh us down and make us weary.  And when life all around us seems to be falling apart and going downhill, spiritual and emotional gravity take their toll on us.  But we are exhorted here to not grow weary, and we are given good reason: God has more than enough strength to provide - to push us forward, Jesus Christ is there drawing, pulling us forward, and the Holy Spirit is within reminding us all the time.  When weary, may we find our strength, hope and courage in the all-powerful, all-knowing, and all-good triune God.
