C.H. Spurgeon: Doctrine and Holiness
My brethren, this is a lesson for us; let us never reckon that we have learned a doctrine till we have seen its bearing upon our lives. Whatever we discover in God’s word, let us pray the Holy Spirit to make us feel the sanctifying influence of it. You know not a man because you recognize his features, you must also know his spirit, and so the mere acquaintance with the letter of truth is of small account — you must feel its influence and know its tendency.
