The cross does not merely inform us of something, something that may be “above,” or “behind” it. It attacks and afflicts us. Knowledge of God comes when God happens to us, when God does himself to us. We are crucified with Christ (Gal 2:19). The sinner, the old being, neither knows nor speaks the truth abou God and consequently can only be put to death by the action of God.
— Gerhard Forde, On Being a Theologian of the Cross (p90)
