Did I not hear some one say, ‘Ah, sir, I have been trying to believe for years.’ Terrible words! They make the case still worse. Imagine that after I had made a statement, a man should declare that he did not believe me, in fact, he could not believe me though he would like to do so. I should feel aggrieved certainly; but it would make matters worse if he added, ‘In fact I have been for years trying to believe you, and I cannot do it.’ What does he mean by that? What can he mean but that I am so incorrigibly false, and such a confirmed liar, that though he would like to give me some credit, he really cannot do it? With all the effort he can make in my favour, he finds it quite beyond his power to believe me? Now, a man who says, ‘I have been trying to believe in God,’ in reality says just that with regard to the Most High . . . The talk about trying to believe is a mere pretence. But whether pretence or no, let me remind you that there is no text in the Bible which says, ‘Try and believe,’ but it says ‘Believe in the Lord Jesus Christ.’ He is the Son of God, he has proved it by his miracles, he died to save sinners, therefore trust him; he deserves implicit trust and child-like confidence. Will you refuse him these? Then you have maligned his character and given him the lie.
Charles Spurgeon (1834 – 1892)
