The Bible is clear that whatever our senses experience will affect our whole body and spirit. So what we experience with our senses actually affect our spirituality, our relation to God. What we see, read, and listen to can either negatively or positively affect how spiritual we are.
Knowing that light and darkness have no common denominator, no reason to share experiences, Matthew 6:22-24 teaches, "The lamp of the body is the eye. If therefore your eye is good, your whole body will be full of light. But if your eye is bad, your whole body will be full of darkness. If therefore, the light that is in you is in darkness, how great is that darkness! No one can serve two masters, for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon."
Many today try to serve God and still walk in darkness. God said these two have no fellowship with each other, it cannot be done. You have to make a decision to follow hard after God and be careful what your senses see, hear, and experience. Because the "lamp of the body is the eye", therefore what you see lights your path, and leads you in that path. If you choose to look at perversion in movies and internet entertainment then that is what will drive you and the path will not lead to God. If you choose to soak up music that is not uplifting to God, then your spirit will be driven by the world's view. If you read books and magazines that are not godly then those values will push you to darkness, not light.
We must beware and heed the warning of Scripture that says we choose the path we take by what we decide to "see". We direct our own lives, with our choices. Joshua declared, "Choose you this day who you will serve."
