"Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin. For we have come to share in Christ, if indeed we hold our original confidence firm to the end."
- Hebrews 3:12-14 ESV
"We are too apt to forget that temptation to sin will rarely present itself to us in its true colors, saying, “I am your deadly enemy — and I want to ruin you forever in Hell!” Oh, no! Sin comes to us, like Judas — with a kiss; and like Joab — with an outstretched hand and flattering words. The forbidden fruit seemed good and desirable to Eve — yet it cast her out of Eden. The walking idly on his palace roof seemed harmless enough to David — yet it ended in adultery and murder. Sin rarely seems sin at its first beginnings. Let us then watch and pray, lest we fall into temptation. We may give wickedness smooth names — but we cannot alter its nature and character in the sight of God. Let us remember Paul’s words: “Exhort one another daily . . . lest any be hardened through the deceitfulness of sin” (Hebrews 3:13)."
- J.C. Ryle, Holiness
"From this first transgression, by which sin entered into the world, we may form some idea of its deceitful nature. This first sin is a sort of example of all other sins. As they flow from this as streams from a fountain, they all partake of the poison of their origin. In all sin there is some bait—some apparent good—some expectation of pleasure or profit from
unlawful indulgence. In all sin the mind is under a delusive influence. Right thoughts and motives are for the moment forgotten or overborne; the attention, like the eye of a beguiled bird, is fixed on a point from which it cannot be withdrawn. The enticement prevails, and guilt is contracted."
- Archibald Alexander, Deceitfulness of Sin
"We are in danger of having too low or light a view of one’s sin and also too light a grasp of what Jesus has done for us." - Tim Keller
"Lord, keep us from sin. 'Lead us not into temptation, but deliver us from evil.' There is no evil like the evil of sin—deliver us from it, O Lord! Alas, we are sadly prone to sin and evil has great influence over us. When I say this, I refer not only to those who are 'dead in trespasses and sins,' in whom sin is the great reigning power—for they are the servants of sin—but I refer also to the people of God. Even we that have been born-again and are, in a measure, sanctified by the Spirit of God—even we, I say—have a fleshly nature whose tendencies are evil, whose desires draw towards sin. How soon we slip! How much we need to be held up! How ought we daily to cry for Divine Grace lest we, also, should be 'hardened through the deceitfulness of sin'!"
