Use sin as it will use you; spare it not, for it will not spare you; it is your murderer, and the murderer of the world: use it, therefore, as a murderer should be used. Kill it before it kills you. You love not death; love not the cause of death.
Spend your time in nothing which you know must be repented of; in nothing on which you might not pray for the blessing of God; in nothing which you could not review with a quiet conscience on your dying bed; in nothing which you might not safely and properly be found doing if death should surprise you in the act.
No vassalage is so ignoble, no servitude so miserable, as that of vice; mines and galleys, mills and dungeons, are words of ease compared to the service of sin; therefore, the bringing sinners to repentance is so noble, so tempting a design, that it drew even God himself from heaven to prosecute it.
Sin is first pleasing, then it grows easy, then delightful, then frequent, then habitual, then confirmed; then the man is impenitent, then he is obstinate, then he is resolved never to repent, and then he is ruined.
Keep God's covenant in your trials; hold you by His blessed word, and sin not; flee anger, wrath, grudging, envying, fretting; forgive a hundred pence to your fellow-servant, because your Lord hath forgiven you ten thousand talents: for, I assure you by the Lord, your adversaries shall get no advantage against you, except you sin, and offend your Lord, in your sufferings.
