There comes a point in religious conversations when the Spirit of God has been replaced by the spirit of contention. When a gospel discussion has reached the point where no progress is being made, then the discussion must end. Giddonah wisely understood that he had reached that point with Korihor. Rather, than get into a “Bible-bash,” he backed off.
Joseph Smith
"Let the Elders be exceedingly careful…Remember that your business is to preach the Gospel in all humility and meekness, and warn sinners to repent and come to Christ.
“Avoid contentions and vain disputes with men of corrupt minds, who do not desire to know the truth. Remember that ’it is a day of warning, and not a day of many words.’ If they receive not your testimony in one place, flee to another, remembering to cast no reflections, nor throw out any bitter sayings. If you do your duty, it will be just as well with you, as though all men embraced the Gospel.” (Teachings of the Prophet Joseph Smith, p. 43, italics added)
