"For in Him dwells all the fullness of the Godhead bodily; and you are complete in Him, who is the head of all principality and power." (Col. 2:9-10) "I am the Alpha and the Omega, the Beginning and the End, the First and the Last." (Rev. 22:13)

Consider the number of words it took to write the thirty-volume set of the Encyclopedia Britannica. Even though there a is momentous number of words, only twenty-six different letters were used. The authors of the Britannica did not need to go outside the alphabet to assemble massive collection of knowledge. The alphabet provided everything they needed to complete their task.

Likewise, Jesus Christ is the Alpha and Omega, and we do not need to go outside of Him for anything we need. We are complete in Him, and He is our "everything" for all situations.
