We know the habit of mind that makes men great in the sciences of this world,--that makes such men as Archimedes, or Sir Isaac Newton, or Galileo, or Ferguson the astronomer, or James Watt. All these were men of one thing. They brought the powers of their minds into one single focus. They cared for nothing else beside. And this was the secret of their success. I say that this same habit consecrated to the service of God becomes religious _zeal_.
We know the habit of mind that makes men rich,--that makes men amass mighty fortunes, and leave millions behind them. What kind of people were the bankers, and merchants, and tradesmen, who have left a name behind them, as men who acquired immense wealth and became rich from being poor? They were all men that threw themselves entirely into their business, and neglected every thing else for the sake of that business. They gave their first attention, their first thoughts, the best of their time, and the best part of their mind, to pushing forward the transactions in which they were engaged. They were men of one thing. Their hearts were not divided. They devoted themselves, body, soul, and mind to their business. They seemed to live for nothing else. I say that if you turn that habit of mind to the service of God and His Christ it makes religious _zeal_.
(_a_) Now this habit of mind,--this zeal was _the characteristic of all the Apostles_. See for example the Apostle Paul. Hear him when he speaks to the Ephesian elders for the last time: "None of these things move me, neither count I my life dear unto myself, so that I might finish my course with joy, and the ministry that I have received of the Lord Jesus, to testify the Gospel of the grace of God." (Acts xx. 24.) Hear him again, when he writes to the Philippians: "This one thing I do; I press towards the mark for the prize of the high calling of God in Christ Jesus." (Phil. iii. 13, 14.) See him from the day of his conversion, giving up his brilliant prospects,--forsaking all for Christ's sake,--and going forth to preach that very Jesus whom he had once despised. See him going to and fro throughout the world from that time,--through persecution,--through oppression,--through opposition,--through prisons,--through bonds,--through afflictions,--through things next to death itself, up to the very day when he sealed his faith with his blood, and died at Rome, a martyr for that Gospel which he had so long proclaimed. This was true religious _zeal_.
(_b_) This again was the _characteristic of the early Christians_. They were men "every where spoken against." (Acts xxviii. 22.) They were driven to worship God in dens and caves of the earth. They often lost every thing in the world for their religion's sake. They generally gained nothing but the cross, persecution, shame, and reproach. But they seldom, very seldom, went back. If they could not dispute, at least they could suffer. If they could not convince their adversaries by argument, at any rate they could die, and prove that they themselves were in earnest. Look at Ignatius cheerfully travelling to the place where he was to be devoured by lions, and saying as he went, "Now do I begin to be a disciple of my Master, Christ." Hear old Polycarp before the Roman Governor, saying boldly, when called upon to deny Christ, "Four score and six years have I served Christ, neither hath He ever offended me in any thing, and how then can I revile my King?" This was true _zeal_.
(_c_) This again was _the characteristic of Martin Luther_. He boldly defied the most powerful hierarchy that the world has ever seen. He unveiled its corruptions with an unflinching hand. He preached the long-neglected truth of justification by faith, in spite of anathemas and excommunications, fast and thickly poured upon him. See him going to the Diet at Worms, and pleading his cause before the Emperor and the Legate, and a host of the children of this world. Hear him saying,--when men were dissuading him from going, and reminding him of the fate of John Huss, "Though there were a devil under every tile on the roofs of Worms, in the name of the Lord I shall go forward." This was true _zeal_.
(_d_) This again was _the characteristic of our own English Reformers_. You have it in our first Reformer, Wickliffe, when he rose up on his sick bed, and said to the Friars, who wanted him to retract all he had said against the Pope, "I shall not die, but live to declare the villanies of the Friars." You have it in Cranmer, dying at the stake, rather than deny Christ's Gospel, holding forth that hand to be first burned which, in a moment of weakness, had signed a recantation, and saying, as he held it in the flames, "This unworthy hand!" You have it in old father Latimer, standing boldly on his faggot, at the age of seventy years, and saying to Ridley, "Courage, brother Ridley! we shall light such a candle this day as, by God's grace, shall never be put out." This was _zeal_.
