And when the East Wind breathes upon these letters on the floor, I see at once that they are symbols of the Invincibility of Jesus. 'I am—A and Z!' He is at the beginning, that is to say, and He goes right through to the end. There is nothing in the alphabet before A; there is nothing after Z. However far back your evolutionary interpretation of the universe may place the beginning of things, you will find Him there. However remote your interpretation of prophecy may make the end of things, you will find Him there. He goes right through. The story of the ages—past, present and future—may be told in a sentence: 'Christ first, Christ last, and nought between but Christ.' Having begun, He completes. He is the Author and Finisher of our faith. He sets His face like a flint. Nothing daunts, deters, or dismays Him. 'I am confident,' Paul says, 'of this very thing, that He which hath begun a good work in you will perform it unto the end.' He never halts at H or L or P or X; he goes right through to Z. He never gives up.
