If we continually persist in committing any of the actions listed above, we are walking by the flesh. Our flesh is in control of our thoughts and therefore our actions. If we are having problems in any of these areas we need to do some heart-searching. We need to allow the Holy Spirit to have control of our thoughts before they become actions. Just as surely as dust enters our homes and settles on our fixtures, so do evil thoughts enter our minds and try to take up residence in our brains. We can choose to wipe the dust away or let it build up. The choice is ours. Our bodies are temples of the Holy Spirit and He certainly does not want any of the world’s junk living with Him. He is there to help us keep the temple clean.
18 But the things that come out of a person’s mouth come from the heart, and these defile them. 19 For out of the heart come evil thoughts—murder, adultery, sexual immorality, theft, false testimony, slander. 20 These are what defile a person; but eating with unwashed hands does not defile them.”–Matt. 15:18-20 (NIV)
