chasing after what is cheap

"Thus it is that no cruelty whatsoever passes by without impact. Thus it is that we always pay dearly for chasing after what is cheap." 

[Aleksandr Solzhenitsyn]

a slave into a child

To see the law of Christ fulfilled
And hear his pard'ning voice
Transforms a slave into a child
And duty into choice. 

[William Cowper]

no mode of victory but by flight

In contending with certain sins there remains no mode of victory but by flight. The ancient naturalists wrote much of basilisks, whose eyes fascinated their victims and rendered them easy victims; so the mere gaze of wickedness puts us in solemn danger. He who would be safe from acts of evil must haste away from occasions of it. A covenant must be made with our eyes not even to look upon the cause of temptation, for such sins only need a spark to begin with and a blaze follows in an instant. Who would wantonly enter the leper's prison and sleep amid its horrible corruption? He only who desires to be leprous himself would thus court contagion. If the mariner knew how to avoid a storm, he would do anything rather than run the risk of weathering it. Cautious pilots have no desire to try how near the quicksand they can sail, or how often they may touch a rock without springing a leak; their aim is to keep as nearly as possible in the midst of a safe channel.

This day I may be exposed to great peril, let me have the serpent's wisdom to keep out of it and avoid it. The wings of a dove may be of more use to me today than the jaws of a lion. It is true I may be an apparent loser by declining evil company, but I had better leave my cloak than lose my character; it is not needful that I should be rich, but it is imperative upon me to be pure. No ties of friendship, no chains of beauty, no flashings of talent, no shafts of ridicule must turn me from the wise resolve to flee from sin. The devil I am to resist and he will flee from me, but the lusts of the flesh, I must flee, or they will surely overcome me. O God of holiness preserve thy Josephs, that Madam Bubble bewitch them not with her vile suggestions. May the horrible trinity of the world, the flesh, and the devil, never overcome us! 

[Charles Spurgeon]

we can go on to peaceableness

"We must set our faces like flints against everything which is contrary to God and His holiness: purity being in our souls a settled matter, we can go on to peaceableness."

 [Charles Spurgeon]

lest that day come upon you suddenly like a trap

"But watch yourselves lest your hearts be weighed down with dissipation and drunkenness and cares of this life, and that day come upon you suddenly like a trap. For it will come upon all who dwell on the face of the earth. But stay awake at all times, praying that you may have strength to escape all these things that are going to take place, and to stand before the Son of Man."

[Luke 21:34-36]
