Jesus said, The Father's imperial rule is like a person who wanted to kill someone powerful. While still at home he drew his sword and thrust it into the wall to find out whether his hand would go in. Then he killed the powerful one. (98 Thomas)

How is God's domain as an assassin?

The assassin is prepared to take a significant risk. The assassin envisions his act. The assassin practically prepares for his act. The assassin takes action.

The assassins best known to those listening to Jesus were the Zealots, terrorist freedom fighters against Roman oppression.

To receive God's domain may require a killing of the self we have known.

In order to know the freedom of God's intention, we may be called to assassinate the self we have become.

Above is Thomas encountering the risen (and headless) Jesus.
