You. Stop. Take a minute and hear this as January sweeps you by:

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. He gives power to the faint, and to him who has no might he increases strength. Even youths shall faint and be weary, and young men shall fall exhausted; 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

Be encouraged: Our God does not grow weary. This isn't His first day on the job, or His first time flipping a year from one to the next.

If you're gonna resolve to do anything this year, might I suggest the thing that will increase your energy and build your strength: wait upon the Lord.
