It has been a real pleasure to hear Paul Tripp preach on Jonah in recent months.  Two of his more memorable lines have been especially thought provoking:

"The anger of God is our only hope."  (because in his implacable opposition to evil, God defeats Satan for our salvation)

"Your theology will not always move you in the direction of obedience because your use of theology is governed by the condition of your heart."  (as good a brief explanation as you will ever hear as to why Christians and churches with otherwise good theology sometimes disappoint)
