We are not called to always show a smile. Sometimes we are called to frown and rebuke with all long-suffering and doctrine. We must contend but not be contentious. We must preserve truth but injure no man. We must destroy error without harming people. In earlier times, when men were wrong, they contended, and in contending, they became contentious. In an attempt to preserve truth, they destroyed those who held error. Let us preserve truth but injure no man.
