The Great Announcement: "All Authority in Heaven and on Earth Has Been Given to Me"
In his opening vision of the Apocalypse, John hears these words from the glorified Son: "Fear not, I am the first and the last, and the living one. I died, and behold I am alive forevermore, and I have the keys of Death and Hades" (Rev. 1:17-18). Just as this triumphant indicative grounds Jesus' imperative, "Write therefore the things you have seen" in this remarkable book (v. 19), his announcement that all authority is in his hands is the rationale for the Great Commission's "Therefore, go...!"
I am a pretty impulsive person. There is a check I need to take to the bank. I rush out the door, jump in the car, and am halfway to my destination when I realize that I've forgotten the check.

Just go. Just do it. "Get 'er done," as they say. Reflection slows you down.
