Another very great obstacle to soul-winning is unbelief. You know that it is written of the Lord Jesus when in "His own country that "He did not many mighty works there because of their unbelief." This evil exists in all unregenerate hearts, but in some men it takes a very pronounced form. They do think about religion, but they do not believe in the truth of God which we preach to them. Their opinion is to them more weighty, more worthy of belief, than God's inspired declarations; they will not accept anything that is revealed in the Scriptures. These people are very hard to influence; but I would warn you not to fight them with their own weapons. I do not believe that infidels ever are won by argument; or, if so, it very seldom happens. The argument that convinces men of the reality of religion, is that which they gather from the holiness and earnestness of those who profess to be Christ's followers. As a rule, they barricade their minds against the assaults of reason and if we give our pulpits over to arguing with them, we shall often be doing more harm than good. In all probability, only a very small portion of our audience will understand what we are talking about; and while we are trying to do them good, most likely we shall be teaching infidelity to others who do not know anything about such things, and the first knowledge they ever have of certain heresies will have come to them from our lips. Possibly our refutation of the error may not have been perfect, and many a young mind may have been tinctured with unbelief through listening to our attempted exposure of it. I believe that you will rout unbelief by your faith rather than by your reason; by your belief, and your acting up to your conviction of the truth, you will do more good than by any argument, however strong it may be.Spurgeon gave a personal story:
There is a friend who sits to hear me generally every Sabbath. "What do you think?" he said to me, one day, "you are my only link with better things; but you are an awful man in my estimation, for you have not the slightest sympathy with me." I replied, "No, I have not; or, rather, I have not the least sympathy with your unbelief." "That makes me cling to you, for I fear that I shall always remain as I am; but when I see your calm faith, and perceive how God blesses you in exercising it, and know what you accomplish through the power of that faith, I say to myself, 'Jack, you are a fool.'" I said to him, "You are quite right in that verdict; and the sooner you come to my way of thinking, the better, for nobody can be a bigger fool than the man who does not believe in God." One of these days I expect to see him converted; there is a continual battle between us, but I never answer one of his arguments. I said to him once, "If you believe that I am a liar, you are free to think so if you like; but I testify what I do know, and state what I have seen, and tasted, and handled, and felt, and you ought to believe my testimony, for I have no possible object to serve in deceiving you." That man would have beaten me long ago if I had fired at him with the paper pellets of reason. So, I advise you to fight unbelief with belief, falsehood with the truth, and never to cut and pare down the gospel to try to make it fit in with the follies and fancies of men.Spurgeon's view reminds me of Jesus' warning:
"Do not give dogs what is holy, and do not throw your pearls before pigs, lest they trample them underfoot and turn to attack you.
(Matthew 7:6 ESV)
