unseen thing. What is that unseen thing? It is that of all unseen
things the most radiant, the most beautiful, the most Divine, and that
is _Character_. On earth, in Heaven, there is nothing so great, so
glorious as this. The word has many meanings; in ethics it can have
but one. Glory is character, and nothing less, and it can be nothing
more. The earth is "full of the glory of the Lord," because it is full
of His character. The "Beauty of the Lord" is character. "The
effulgence of His Glory" is character. "The Glory of the Only
Begotten" is character, the character which is "fullness of grace and
truth." And when God told His people _His name_, He simply gave them
His character, His character which was Himself: "And the Lord
proclaimed the name of the Lord ... the Lord, the Lord God, merciful
and gracious, long-suffering and abundant in goodness and truth."
Glory then is not something intangible, or ghostly, or transcendental.
If it were this, how could Paul ask men to reflect it? Stripped of its
physical enswathement it is Beauty, moral and spiritual Beauty, Beauty
infinitely real, infinitely exalted, yet infinitely near and
infinitely communicable.

With this explanation read over the sentence once more in paraphrase:
We all reflecting as a mirror the character of Christ are transformed
into the same Image from character to character--from a poor character
to a better one, from a better one to a little better still, from that
to one still more complete, until by slow degrees the Perfect Image is
attained. Here

THE SOLUTION OF THE PROBLEM OF SANCTIFICATION

is compressed into a sentence: Reflect the character of Christ, and
you will become like Christ. You will be changed, in spite of yourself
