"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 40:29-31. We find it hard to wait because in our society waiting equates to getting nothing done - procrastinating - laziness, but waiting on the Lord is active waiting, not empty waiting, and it's where God renews our strength.
