The objective of the [Paul’s] life—that for which he sacrificed everything—country, kindred, honor, comfort, liberty, and life itself, was that he might know Christ! Observe that this is not Paul’s prayer as an unconverted man— that he may know Christ, and so be saved—for it follows upon the previous supplication that he might win Christ, and be found in Him. This is the desire of one who has been saved, who enjoys the full conviction that his sins are pardoned, and that he is in Christ. It is only the regenerated and saved man who can feel the desire, “That I may know Him.”
