The apostle Paul spoke of man's internal conflict, the spirit vs. the flesh at
(ROMANS 7:21-23) 21 I find, then, this law in my case: that when I wish to do what is right, what is bad is present with me. 22 I really delight in the law of God according to the man I am within, 23 but I behold in my members another law warring against the law of my mind and leading me captive to sin’s law that is in my members.

We all go through this at some point in our lives. I'm going through it right now.
