The cross is where God meets humanity where it is - on the way to the grave. Paradoxically, where God looks least recognizable is where God is most fully revealed.
At the cross, God is being an iconoclast of himself. At the cross, God destroys all of the preconceived notions of what God is like; all-powerful, all-knowing and transcendent.
In being crucified, Jesus returns the experience and realities of suffering, pain, humiliation and abandonment to what is the triune life of God. It is difficult to understate the theological and existential importance of the reality that God suffers along with us, continually.
