Sin, in being contrary to God, is contrary to man, for what crosses God’s glory is opposed to man’s happiness.

Be as willing to die to sin as Christ was to die for sin, and as willing to live to Him as He was to die for you. Be as willing to be His, to serve Him, as that He should be yours to save you. Take Him on His own terms, give up yourself wholly to Him.

To be merciful to [indwelling] sin is to be cruel to yourself.

Reproving others is a thankless office and an unwelcome work for the most part; men take reproofs for reproaches, yet since God has laid it on good men as their duty to rebuke and not suffer sin to lie upon their brother, they dare not omit it.
