John Owen – A Treatise on Indwelling Sin Chapter 1

Awake, therefore, all of you in whose hearts is any thing of the ways of God ! Your enemy is not only upon you, as on Samson of old, but is in you also. He is at work, by all ways of force and craft, as we shall see.
Would you not dishonor God and his gospel; would you not scandalize the saints and ways of God; would you not wound your consciences and endanger your souls; would you not grieve the good and holy Spirit of God, the author of all your comforts; would you keep your garments undefiled, and escape the woful temptations and pollutions of the days wherein we live; would you be preserved from the number of the apostates in these latter days; — awake to the consideration of this cursed
enemy, which is the spring of all these and innumerable other evils, as also of the ruin of all the souls that perish in this world!John Owen Indwelling Sin Chapter 1
