Many things which are not sinful also have some sort of "addictive" effect. You do them once and then every now and then you feel the desire to do it again. For example when you have a hobby or something else which is fun then after starting to do it you'll find yourself wanting to do it again. If this wasn't a non-sinful hobby but some sort of sinful activity then everybody would directly say that this is some sort of bondage or addiction or simply the flesh which is being tempted, right? But what I ask myself is where is the difference between wanting to do something which isn't a sin again and again and being tempted to do a sin again and again? Could it be that the mechanisms are the same and it doesn't even matter if it's a sinful activity or not? I mean where is the difference between wanting to play with your dog or wanting to play an instrument and getting the desire to sin? Are both desires triggered by the same mechanism? Isn't it in both cases the flesh which wants to do these things? I mean what I ask myself is simply this: Not everything which has some sort of habitual effect on people is directly a sin. When you do something which is fun then you will want to repeat it but this doesn't mean it's a sin. But if it was a sin then christians would directly explain this behavior with the fact that it's a sin and that sin creates bondage. But what if this explanation is wrong because not everything which creates the desire to be repeated automatically is a sin.
