Rules Of A Godly Life: Part 2: Rule 9

"Do not make fun of another's weaknesses. Instead, think of your own shortcomings. Gal. 6. We all have our weak points, and there is none of whom others say not, "O that this or that were different." Either we are, or have been, or may become subject to most anything, even as others. Therefore, show patience and sympathy toward your brother's weaknesses and mistakes. At the same time, do not strengthen him in sin by your nonchalance or by neglecting brotherly admonition and reproof. If you wish to admonish a brother, be careful to bring your reproof at a suitable time; for a reproof at the wrong time may easily do more harm than good, especially if the rebuke is too sharp or not tempered with gentleness. A reproof is like a salad, it needs more oil than vinegar."
