Jesus parted company with the authorities, not because he wished to but because they did. His warm, open-handed approach to others provoked in the authorities an angry, clench-fisted reaction. To preserve the status quo they would have to be rid of this challenging presence.
The crucifixion was meant to silence him for good. Instead, it gave him the last word. It not only capped his life of sacrifice but raised up an iconic sign to inspire us over the centuries.
The sacrifice of Jesus shows the price to be paid if we are to reach peace he calls us to.
