Convictions based just on what our parents believe may work for a time; convictions based on personal experiences may help with some situations; convictions based on personal opinions may at times guide us in decisions; and even convictions based on the values of the world may in a rare situation also honor God; but by far the best, the strongest, and the surest conviction that will guide us in every situation, decision, and temptation is a conviction formed by sound and thorough biblical study and teaching.
