Theological truth is the truth of God's relationship with man and it is the fruit not of learning but of experience. In this sense all theology, properly so called, is written in blood. It is an attempt to communicate what has been discovered at great cost in the deepest places of the heart - by sorrow and joy, frustration and fulfillment, defeat and victory, agony and ecstasy, tragedy and triumph. Theology, properly so called, is the record of a man's wrestling with God. Wounded in some way or other by the struggle the man will certainly be, but in the end he will obtain the blessing promised to those who endure.
The theologian in this respect is no different from the poet or dramatist. All of them must write in blood.
