22. Paul, you will observe, does not consider the Christian absolutely free from sin, since he beseeches us to be "transformed by the renewing of the mind." Where transformation and renewal are necessary, something of the old and sinful nature must yet remain. This sin is not imputed to Christians, because they daily endeavor to effect transformation and renovation. Sin exists in them against their will. Flesh and spirit are contrary to each other (Gal 5, 17), therefore we do not what we would. Rom 7, 15. Paul makes particular mention of "the mind" here, by contrast making plainer what is intended by the "body" which he beseeches them to sacrifice. The scriptural sense of the word "mind" has already been sufficiently defined as "belief," which is the source of either vice or virtue. For what I value, I believe to be right. I observe what I value, as do others. But when belief is wrong, conscience and faith have not control. Where unity of mind among men is lacking, love and peace cannot be present; and where love and faith are not present, only the world and the devil reign. Hence transformation by renewal of the mind is of vital importance. Now follows: SOBER THOUGHTS OF OURSELVES. "For I say, through the grace that was given me, to every man that is among you, not to think of himself more highly than he ought to think; but so to think as to think soberly, according as God hath dealt to every man a measure of faith." 23. Paul, in all his epistles, is careful to give this instruction to Christians. His purpose is to preserve simplicity of faith among them everywhere; to prevent sects and schisms in Christian life, which have their origin in differing minds, in diversity of belief. To make admonition the more forcible, he refers to his apostolic office; to the fact that he was, by the grace of God, chosen and sent to teach the things he advocates. His words here mean: "Ye possess many graces, but let everyone take heed to confine his belief and opinions to the limits of faith. Let him not esteem himself above another, nor attach to the gifts conferred upon himself greater value than he accords those conferred upon another. Otherwise he will be inclined to despise the lesser gifts and emphasize the more exalted ones, and to influence others to the same practice." Where there is not such humility, recourse is had to works and to the honoring of gifts, while faith is neglected. Thus belief prompts to do as the world does, to value what is exalted and to despise what is humble.
