Seeing you have purified your souls in your obedience to the truth through the Spirit in sincere brotherly affection, love one another from the heart fervently:
 (3) The agency by which this was accomplished was that of the Holy Spirit. Truth is adapted in itself to a certain end or result, as seed is adapted to produce a harvest. But it will no more of itself produce its appropriate effects on the soul, than seed will produce a harvest without rains, and dews, and suns. In all cases, therefore, the proper effect of truth on the soul is to be traced to the influence of the Holy Spirit, as the germination of the seed in the earth is to the foreign cause that acts on it. No man was ever converted by the mere effect of truth without the agency of the Holy Spirit, any more than seed germinates when laid upon a hard rock.
