Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God; but exhort one another daily, while it is called “Today,” lest any of you be hardened through the deceitfulness of sin. For we have become partakers of Christ if we hold the beginning of our confidence steadfast to the end, while it is said: “Today, if you will hear His voice, do not harden your hearts as in the rebellion.” Hebrews 3:12-15
“The great sin of not believing in the Lord Jesus Christ is often spoken of very lightly and in a very trifling spirit, as though it were scarcely any sin at all; yet, according to my text, and, indeed, according to the whole tenor of the Scriptures, unbelief is the giving of God the lie [calling God a liar], and what can be worse?” (Spurgeon)
“Hearken, O unbeliever, you have said, ‘I cannot believe,’ but it would be more honest if you had said, ‘I will not believe.’ The mischief lies there. Your unbelief is your fault, not your misfortune. It is a disease, but it is also a crime: it is a terrible source of misery to you, but it is justly so, for it is an atrocious offense against the God of truth.” (Spurgeon)
“Did I not hear someone 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.” (Spurgeon)
“You are to watch over your brethren, to exhort one another daily, especially you who are officers of the church, or who are elderly and experienced. Be upon the watch lest any of your brethren in the church should gradually backslide, or lest any in the congregation should harden into a condition of settled unbelief, and perish in their sin. He who bids you take heed to yourself, would not have you settle down into a selfish care for yourself alone, lest you should become like Cain, who even dared to say to the Lord himself, ‘Am I my brother’s keeper?’ ” (Spurgeon)
