Context: We have no spiritual need except for a restoration of the divine nature in us. And if this be true, then nothing can be our salvation except that which brings us into a right relationship with God, making us partakers of the divine nature in such a manner and degree as we need. But to reason about life cannot communicate it to the soul, nor can a religion of rational notions and opinions logically deduced from Scripture words bring the reality of the gospel into our lives. Do we not see sinners of all sorts, and men under the power of every corrupt passion, equally zealous for such a religion? How is it then that Christian leaders spend so much time reasoning about Scripture doctrines, and yet remain so blind to the obvious fact that filling the head with right notions of Christ can never give to the heart the reality of His Spirit and life? For logical reasoning about Scripture words and doctrines will do no more to remove pride, hypocrisy, envy, or malice from the soul of man, than logical reasoning about geometry. The one leaves man as empty of the life of God in Christ as the other. Yet the church is filled with professing Christians whose faith has never gone beyond a conviction that the words of Scripture are true. They believe in the Christ of the Bible, but do not know Him personally. The indwelling of the Holy Spirit is sound doctrine to their minds, but their lives are empty of His manifest power either to overcome the power of sin within, or to convert others to Christ. Though many are zealous to preach the gospel, yet instead of bringing men to Christ, they seek to reason them into a trust in their own learned opinions about Scripture doctrines. In contrast to Paul, their gospel is in word only, without the demonstration and power of the Spirit. Nor can they see their need of the Holy Spirit to fill them with Christ, and then to overflow through them in rivers of living water to others, because reason tells them that they are sound in the letter of doctrine.
