They war within us. I know my name could be substituted for Paul's.
The Answer, for Christians, is explained in Romans 8.Romans 7:14-25
<sup id="en-NASB-28106">14</sup>For we know that the Law is spiritual, but I am of flesh, sold into bondage to sin. <sup id="en-NASB-28107">15</sup>For what I am doing, I do not understand; for I am not practicing what I would like to do, but I am doing the very thing I hate.
<sup id="en-NASB-28108">16</sup>But if I do the very thing I do not want to do, I agree with the Law, confessing that the Law is good.
<sup id="en-NASB-28109">17</sup>So now, no longer am I the one doing it, but sin which dwells in me.
<sup id="en-NASB-28110">18</sup>For I know that nothing good dwells in me, that is, in my flesh; for the willing is present in me, but the doing of the good is not.
<sup id="en-NASB-28111">19</sup>For the good that I want, I do not do, but I practice the very evil that I do not want.
<sup id="en-NASB-28112">20</sup>But if I am doing the very thing I do not want, I am no longer the one doing it, but sin which dwells in me.
<sup id="en-NASB-28113">21</sup>I find then the principle that evil is present in me, the one who wants to do good.
<sup id="en-NASB-28114">22</sup>For I joyfully concur with the law of God in the inner man,
<sup id="en-NASB-28115">23</sup>but I see a different law in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin which is in my members.
<sup id="en-NASB-28116">24</sup>Wretched man that I am! Who will set me free from the body of this death?
<sup id="en-NASB-28117">25</sup>Thanks be to God through Jesus Christ our Lord! So then, on the one hand I myself with my mind am serving the law of God, but on the other, with my flesh the law of sin.
