I was recently reminded of this by a patient dying of aids who was filled with tatoos. At a couple of places there was a signiture 'property of so and so, thus claiming ownership of that person. The person who did that was heavily into the occult and the tattoos reflected that.
 
This reminded me of something I learned during deliverance. There are unseen tattoos that spirits can put on people. God also places his mark as in Ephesians 1 where it states we are sealed by the Holy Spirit. That draws attention in the spirit world and we Christians are certainly aware of that.
 
Consider this spirit tattoo. You do something you shouldnt and a spirit tags you. This tag draws other spirits and soon you are swamped with people or material that drives you in a certain wrong direction. The Lord tells us not to give the devil a foothold but we do. Ever gone to the store and found yourself turning around to look at someone and that person just happens to look at you at the same time? Is that just coincidence or are the spirits within us making a connection. We as Christians can allow wrong spirits to hang around us if we are not careful, they then draw our attention in the wrong way. Conversly the Holy Spirit can grab our attention the same way. Our old habits sometimes die hard. For instance we may unconsciously do something that draws attention. For example a lady may have a certain mannerism that attracts men, such as the way they walk or acting flirtatious. It may have become so ingrained that they no longer realize they are doing it unless someone tells them. Guys do the same thing. Though we are saved God tells us to no longer conform to the world, perhaps some of what I have just mentioned are the reasons some of us have such difficulty in our walk.
Something to think about.
God bless frank
