Acts 26:9

I verily thought with myself; in persecuting Christ, Paul was sincere in his error; but this did not make him guiltless, for his belief had its foundation in a wrong state of heart. Had he been humble, candid, and teachable, the evidence which Jesus gave of his Messiahship would have carried full conviction to his mind.

Contrary to the name; in opposition to the teachings and to the followers of Christ. Conscience is not always a safe guide. It must be enlightened by the word and Spirit of God, and accompanied with a pious heart. All should feel this, and so acknowledge God, that he may direct their paths, guide them in judgment, and teach them his way-that way of pleasantness, that path of peace. Proverbs 3:6; Psalms 25:9.
