To be an ethereal figure who merely talked about God, but somehow refused to get his hands dirty in the real world in which God had placed him, was bad theology. Through Christ, God had shown that he meant us to be in this world and to obey him with our actions in this world. So Bonhoeffer would get his hands dirty, not because he had grown impatient, but because God was speaking to him about further steps of obedience.
