September 3:

September 3d. 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 one 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. The Changed Life, p.24.
