“A sinner without grace is a slave: he cannot deliver himself from his sins.” - Charles Spurgeon
"Brothers and sisters, look at what sin has done for us and all of our race. It made that beautiful Eden, which was our garden of delight, to be a wilderness, and made us to be the children of toil and sorrow. What has sin done for us? It has stripped us of our beauty, it has put us away from God, it has set the flaming cherubim with the drawn sword to keep us back from coming near to God, as long as we live in sin. Sin has wounded us, spoiled us, killed us, corrupted us. Sin has brought disease into the world, and digged the grave, and bred the worm. O sin, thou art the mother of all the griefs and groans and sighs and tears that ever befell men and women in this world." - C.H. Spurgeon
“When I look into my heart and take a view of its wickedness, it looks like an abyss infinitely deeper than hell. And it appears to me, that, were it not for free grace, exalted and raised up to the infinite height of all the fulness and glory of the great Jehovah, I should appear sunk down in my sins below hell itself; far below the sight of everything, but the eye of sovereign grace, that alone can pierce down to such a depth. And it is affecting to think how ignorant I was, when a young Christian of the bottomless depths of wickedness, pride, hypocrisy and deceit left in my heart” (1743 A.D.). - Jonathan Edwards
"Prayer will make a man cease from sin, or sin will entice a man to cease from prayer." - John Bunyan
"The Christianity which is from the Holy Spirit will always have a very deep view of the sinfulness of sin. It will not merely regard sin as a blemish and misfortune, which makes men and women objects of pity, and compassion. It will see in sin the abominable thing which God hates, the thing which makes people guilty and lost in his Maker’s sight, the thing which deserves God’s wrath and condemnation. It will look on sin as the cause of all sorrow and unhappiness, of strife and wars, of quarrels and contentions, of sickness and death – the curse which cursed God’s beautiful creation, the cursed thing which makes the whole earth groan and struggle in pain. Above all, it will see in sin the thing which will ruin us eternally, unless we can find a ransom, – lead us captive, except we can get its chains broken, – and destroy our happiness, both here and hereafter, except we fight against it, even unto death."

Tract: Authentic Religion
Let us beware of the beginnings of backsliding, however small. We never know what we may come to, if we once leave the king’s highway. The professing Christian who begins to say of any sin or evil habit, “it is but a little one,” is in imminent danger. He is sowing seeds in his heart, which will one day spring up and bear bitter fruit. It is a homely saying, that “if men take care of the pence the pounds will take care of themselves.” We may borrow a good spiritual lesson from the saying. The Christian who keeps his heart diligently in little things shall be kept from great falls.
