It's easy for us to try to justify our sin, even as believers. When we are tempted by something that we really want, it's easy to try to rationalize it or minimize it. One way to combat this is to know scripture so thoroughly that the Holy Spirit will convict us - and then, of course, to listen to our conscience.
Another key point in this passage is that it is a choice. We always have a choice. We choose whether we will give in to our sinful desires, or to turn away. We choose whether or not we will be faithful. But we have to remember - we are free to choose, but we are not free from the consequences of that choice.
May we be determined to live by God's regulations!
