A great quote from Jack Miller (in The Heart of a Servant Leader):

Not only endure in ministry but blossom with thankfulness and praise...I like to think of repentance and praise as allied to each other - both forms of sanity. Repentance is a return to God as my centre. Praise is the lifting up of God in honour as my centre. But to move away from the centre without repentance or praise is to be eccentric, irrational and insane. But what a simple thing it is to humble the heart and return to sanity by repentance and praise.
