When this world seem to have a hold on you and your situations just don't look as if they have an end. bow your head and lift up your voice and give God the praise and glory and then remember.
(Isaiah 40:31) But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagle;they shall run, and not be weary; and they shall walk, and not faint.
For we are the vessels of God that carries the gospel of the Son Jesus Christ. And when we speak our voices minister to the lost. It carry a familar sound known only to sheep of Son's flock.
