If it were only the exercise of the body, the moving of the lips, the bending of the knee, men would as commonly step to heaven as they go to visit a friend: but to separate our thoughts and affections from the world, to draw forth all our graces, and engage each in its proper object, and to hold them to it till the work prospers in our hands, this, this is the difficulty.
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.
