Emil Brunner- On Doubt

Many have the idea that doubt belongs to life and cannot be helped, that it belongs even to the Christian life. But the truth is that so long as we are in bondage to this doubt we are not yet Christians. For to doubt eternal life is to dismiss the promises of God, to be dis- obedient to the Word of God, to put our trust in our own understanding and senses. God’s Word is not sufficient guarantee, we want something more certain. But this desire for something more certain than God’s Word is doubt, crass, naked doubt; crass, naked paganism; crass, naked Godlessness. — Emil Brunner
