From the updated edition of My Utmost For His Highest (is that kinda like the NIV version of it?)

Every time you venture out in your life of faith, you will find something in your circumstances that, from a commonsense standpoint, will flatly contradict your faith.  But common sense is not faith, and faith is not common sense.  In fact, they are as different as the natural and the spiritual.  Can you trust Jesus where your common sense cannot trust Him? Can you venture out with courage on the words of Jesus, while the realities of your commonsense life continue to shout “It’s all a lie”? ……

Faith must be tested, because it can only become your intimate possession through conflict…

Believe steadfastly on Him and everything that challenges you will strengthen your faith.  There is continual testing in the life of faith up to the point of our physical death, which is the last great test.  Faith is absolute trust in God-trust that could never imagine that He would forsake us. (see Hebrews 13:5-6)

Oswald Chambers was da man.
