"For the flesh sets its desire against the Spirit, and the Spirit against the flesh; for these are in opposition to one another, so that you may not do the things that you please." -Galatians 5:17
There is a common reflection and understanding in our culture that if something feels or seems natural, it must be right.
A few problems arise here. First, some things only feel natural when they are not, in fact, natural. Some of these things might be unnatural and we want to believe they are. So we disregard what really might be true. Other things we have to realize disorders for what they really are. Our brains and hearts can be very deceptive.
On another hand, just because something may be natural does not make it okay or even best for us. I crave a lot of things that are not good for me, but my cravings are natural reactions in me for pleasurable things.
But finally, there is the understanding that our flesh, which is our natural state, is at war within us against the Spirit. Living my life lead by the Spirit is going to oppose all the natural cravings within me. When compared to the pursuit of the Holy Spirit life, we come realize why and how everything else is so much LESSER.
Those natural things inside us oppose the Spirit within us, and moment by moment we choose which to do. Those cravings are more powerful than we give credit. When we disregard how powerful those cravings are, we will likely begin following them naturally, and in so doing, have already begun opposing the Spirit within us. Those are the moments we get discouraged and wonder why or how we have come to do things we do not want to do.
Our cravings are strong, and they may even be natural, but they oppose the Spirit in us. We have to want the Spirit more than what feels natural.
