No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. (KJV)

“I have the right to do anything,” you say—but not everything is beneficial. “I have the right to do anything”—but I will not be mastered by anything. (NIV)

Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: (KJV)

Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. (ESV)

For I do not understand my own actions. For I do not do what I want, but I do the very thing I hate. (ESV)

So now it is no longer I who do it, but sin that dwells within me. For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out. For I do not do the good I want, but the evil I do not want is what I keep on doing. Now if I do what I do not want, it is no longer I who do it, but sin that dwells within me.

So I find it to be a law that when I want to do right, evil lies close at hand. For I delight in the law of God, in my inner being, but I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members. (ESV)

Wretched man that I am! Who will deliver me from this body of death? (ESV)
