When sin lets us alone we may let sin alone; but as sin is never less quiet than when it seems to be most quiet, and its waters are for the most part deep when they are still, so ought our contrivances against it to be vigorous at all times and in all conditions, even where there is least suspicion.
John OwenOnly what God has commanded in His word should be regarded as binding; in all else there may be liberty of actions.
John OwenConsider who and what you are; who the Spirit is that is grieved, what he has done for you, what he comes to your soul about, what he has already done in you; and be ashamed. Among those who walk with God, there is no greater motive and incentive unto universal holiness, and the preserving of their hearts and spirits in all purity and cleanness than this: That the blessed Spirit, who has undertaken to dwell in them, is continually considering what they give entertainment in their hearts unto, and rejoices when his temple is kept undefiled.
