"For all of its joy and celebration and for all of its gifts of life and grace, the Kingdom of God is a kingdom of sacrifice. The central event in the history of this kingdom is a shocking and unthinkable sacrifice. This moment of sacrifice confounded the followers who were there to see it and has interested theologians ever since. It is at once the most terrible and most beautiful event in the kingdom. It is a sacrifice that makes perfect sense and no sense at all. And this sacrifice forms the operating agenda of the kingdom from that time on.
"Jesus, by his bleeding and broken body on the cross, not only gave the kingdom of God its life and hope, but its paradigm for living as well. That history-changing death on the cross is also the life-changing call of Christ to everyone who would follow him. And as it did on the cross, that willingness to die will always result in life. This kingdom is a kingdom of the cross, and everyone who celebrates that sacrifice is called to drag a cross along with them every day.”
(Paul David Tripp, A Quest for More, p. 178)
