I love Jacques Ellul. I should have made the trip to Bordeaux while he was alive and tried to talk to him. I imagine his conversation would have been highly enlightening. Here he is on realistic thinking and spontaneity:
Second, Christian realism means knowing clearly what one is doing. Naturally I do not deny that the Holy Spirit may intervene and give direction to our action; but the possibility of the Spirit’s intervention is no justification for rushing pell-mell into action, just for the sake of action; for yielding to some emotion, sentiment, visceral reaction, on the plea that “God will turn it to account” or, worse, in the conviction that this visceral reaction is tantamount to a divine commandment or a prophetic insight. Christian realism demands that a man understand exactly what he is doing, why he is doing it, and what the results of his doing will be. The Christian can never act spontaneously, as though he were an Illuminist. He must be harmless as the dove (the sacrificial victim, ready to sacrifice himself in his action — for the dove is the sacrificial victim ) and wise as the serpent ( that is, fully aware of just what he thinks and does). He must use the light of reason, of science and technology, to get his bearings, for the “children of this world are wiser than we.” He must be the careful architect who, in accordance with Jesus’ advice, sits down to work out plans and calculate the cost before starting to build. All of which is to say that, contrary to widely held opinion, faith in the Holy Spirit does not mean that we may act imprudently, close our eyes and refuse to think; rather, it means that we must use our heads and try to see with clarity. True, the Holy Spirit — who is clarity itself — may propel us into the greatest imprudence; but then we shall know it.
This is from his brilliant essay on the christian and violence. Click here for the link.
