When we realize a constant enemy of the soul abides within us, what diligence and watchfulness we should have! How woeful is the sloth and negligence then of so many who live blind and asleep to this reality of sin. There is an exceeding efficacy nad power in the indwelling sin of believers, for it constantly inclines itself towards evil. We need to be awake, then, if our hearts would know the ways of God. Our enemy is not only upon us, as it was with Samson, but it is also in us.

Believers obey Christ as the one whom our obedience is accepted by God. Believers know all their duties are weak, imperfect, and unable to abide in God's presence. Therefore they look to Christ as the one who bears the iniquity of their holy things, who adds incense to their prayers, gathers out all the weeds from their duties and makes them acceptable to God.

Mortification is the soul's vigorous opposition to self, wherein sincerity is most evident.

Let no man think to kill sin with few, easy, or gentle strokes. He who hath once smitten a serpent, if he follow not on his blow until it be slain, may repent that ever he began the quarrel. And so he who undertakes to deal with sin, and pursues it not constantly to the death.

A man may be carried on in a constant course of mortification all his days; and yet perhaps never enjoy a good day of peace and consolation.

Temptation is like a knife, that may either cut the meat or the throat of a man; it may be his food or his poison, his exercise or his destruction

Great winds and storms help fruit-bearing trees. So also do corruptions and temptations help the fruitfulness of grace and holiness. The storm loosens the earth round its roots so the tree is able to get its roots deeper into the earth, where it receives fresh supplies of nourishment. But only much later will it be seen to bring forth better fruit. So corruptions and temptations develop the roots of humility, self-abasement and mourning in a deeper search for that grace by which holiness grows strong. But only later will there be visible fruits of increased holiness.
