And our Lord and Master is the connecting link between God and man, through whom God's own Holy Spirit is poured like a mighty flood into the hearts and lives of men, transfiguring them and filling them with the divine power. This is the biblical idea of Christianity; man, through Christ, flooded and permeated and interpenetrated with the Holy Spirit of God. And thus Paul is dead and yet alive, but fully possessed and dominated by the spirit of Christ. Alive as never before, and yet his every thought, word, and deed is really that of his great leader. Can you talk of self-denial to such a Christian? He had forgotten that such a man as Saul of Tarsus or Paul ever existed; he lives only in his Master's work, and is transfigured by it. This, and nothing less, is Christianity, and this is the very highest and grandest heroism. Paul conquers Europe single-handed, alone he stands before Cæsar's tribunal, and yet he is never alone; and from the gloom of the Mammertine dungeon he sends back a shout of triumph. And Peter walks steadily, cheerfully, and unflinchingly, in the footsteps of his Master to share his cross. Let us, before leaving this topic, notice carefully just what religion, and especially Christianity, is not. 1. It is not merely opinion or intellectual belief in a creed. This may be good, or even necessary, but it is not religion. "Thou believest that there is one God; thou doest well: the devils also believe and tremble." We speak with pride, sometimes, of our puissant Christendom, so industrious, so intelligent, so moral, with its ubiquitous commerce, its adorning arts, its halls of learning, its happy firesides, and its noble charities. And yet what is our vaunted Christendom but a vast assemblage of believing but disobedient men? Said William Law to John Wesley, "The head can as easily amuse itself with a living and justifying faith in the blood of Jesus as with any other notion." The most sacred duty may degenerate into a dogma, asking only to be believed. "I go, sir," answered the son in the parable, "but went not." 2. It is not mere feeling. It is neither hope of heaven's joy, nor fear of hell's misery. It may rightly include these, but it is vastly more and higher. It is neither ecstasy nor remorse. The most resolutely impenitent sinner can shout "Hallelujah," and "Woe is me," as loudly as any saint. Now feeling is of vast importance. It stands close to the will and stimulates it, but it is not conformity. The will must be aroused to a robust life.
