If you have ever known someone that would ask forgiveness (sometimes, even before church), then turn around and do same thing again, you are not alone.
Though, that is not anything new to God. We do same thing to Him, all time, "I am sorry for my sin, please forgive me, and I will try to do better." And, maybe we do try, really try. Only, we fail, again.
We want to be a better person. However, when 'we' try to do improving, it is a form of works ~ as if we could actually become good enough. None-the-less, as long as there is some secret part in us that wants temptation, it will come back again and again.
Once we see sin for ugliness that it is (realizing sin is what put Jesus on cross) and we no longer want to dishonor God with temptation even in our thoughts, all we have to do is to ask God to remove it. God always answers true desires of our heart. We no longer need beg to be made good enough and giving it to God makes Him Divine Keeper. Satan is no longer aloud to tempt us, in that way, ever again!
It is not hard to walk a pure life once we have made our heart pure. But otherwise, we are destined to fail. Though, how we let another's sin affect us is a different matter.

Throughout state of KY, people are not prepared for harsh winter weather, as it happens too seldom for them to see reason in financing labor and equipment. So, being that one cannot get up or down even smallest icy hills, as truckers well know, state is pretty much at a stand still until snow and ice melts; good part being that winter thaws much quicker than it does farther north.
For three years, my family and I lived in KY ~ where I worked retail. If snow clouds even appeared, employees would periodically go stand at door (all day long), where they could check to see if anything had changed in weather. And, at first snow flake, employees verbally expressed worrying about weather throughout remaining of entire work day. To those accustomed to more northern exposure, it was as if these people had never seen snow before. And for all purposes, it seemed so, as they had no clue how to drive in it.
Observing them caused me to realize how truly foolish it is to let weather effect our day. If it so much as rains, people are depressed. Yet, how else will grass, flowers, and trees get water? Otherwise, there would be no beauty for us to enjoy and beautiful KY mountain sides would turn into mud slides at winter's thaw.
