What then is the killing of sin? It is the constant battle against sin which we fight daily-the refusal to allow the eye to wander, the mind to contemplate, the affections to run after anything which will draw us away from Christ. It is the deliberate rejection of any sinful thought, suggestion, desire, aspiration, deed, circumstance or provocation at the moment we become conscience of its existence.
