I love this quote from Andrew Murray that Randy Alcorn mentioned in a recent article:
Learn to worship God as the God who does wonders, who wishes to prove in you that He can do something supernatural and divine.
Bow before Him; wait upon Him, until your soul realizes that you are in the hands of a divine and almighty worker.
Consent not to know what and how He will work; expect it to be something altogether godlike.
He is teaching you to leave all in His hands, and to wait on Him alone. —Andrew Murray
