From J. C. Ryle:
The Christianity which I call fruit-bearing, that which shows its Divine origin by its blessed effects on mankind – the Christianity which you may safely defy unbelievers to explain away – that Christianity is a very different thing. Let me show you some of its leading marks and features.
(1) Fruit-bearing Christianity has always taught the inspiration, sufficiency, and supremacy of Holy Scripture. It has told people that God’s Word written is the only trustworthy rule of faith and practice in religion, that God requires nothing to be believed that is not in this Word, and that nothing is right which contradicts it. It has never allowed reason, a person’s mind, or the voice of the Church, to be placed above, or on a level with Scripture. It has steadily maintained that, however imperfectly we may understand it, the Old Book is meant to be the only standard of life and doctrine.
(2) Fruit-bearing Christianity has always taught fully the sinfulness, guilt and corruption of human nature. It has told people that they are born in sin, deserve God’s wrath and condemnation, and are naturally inclined to do evil. It has never allowed that men and women are only weak and pitiable creatures, who can become good when they please, and make their own peace with God. On the contrary, it has steadily declared a person’s danger and vileness, and their pressing need of a Divine forgiveness and satisfaction for their sins, a new birth or conversion, and an entire change of heart.
(3) Fruit-bearing Christianity has always set before people the Lord Jesus Christ as the chief object of faith and hope in religion, as the Divine Mediator between God and humanity, the only source of peace of conscience, and the root of all spiritual life. It has never been content to teach that He is merely our Prophet, our Example, and our Judge. The main things it has ever insisted on about Christ are the atonement for sin He made by His death, His sacrifice on the cross, the complete redemption from guilt and condemnation by His blood, His victory over the grave by His resurrection, His active life of intercession at God’s right hand, and the absolute necessity of simple faith in Him. In short, it has made Christ the Alpha and the Omega in Christian theology.
(4) Fruit-bearing Christianity has always honored the Person of God the Holy Spirit, and magnified His work. It has never taught that all professing Christians have the grace of the Spirit in their hearts, as a matter of course, because they are baptized, or because they belong to the Church, or because they partake of Holy communion. It has steadily maintained that the fruits of the Spirit are the only evidence of having the Spirit, and that those fruits must be seen, – that we must be born of the Spirit, led by the Spirit, sanctified by the Spirit, and feel the operations of the Spirit, – and that a close walk with God in the path of His commandments, a life of holiness, charity, self-denial, purity, and zeal to do good, are the only satisfactory marks of the Holy Spirit.
Summary ► Such is true fruit-bearing Christianity. Well would it have been for the world if there had been more of it during the last nineteen centuries! Too often, and in too many parts of Christendom, there has been so little of it, that Christ’s religion has seemed extinct, and has fallen into utter contempt. But just in proportion as such Christianity as I have described has prevailed, the world has benefited, the unbeliever has been silenced, and the truth of Divine revelation been acknowledged. The tree has been known by its fruit.
