Associations.

As the saying goes, "Show me your friends and I will predict your future". We are a summation of our thinking which is influenced by the environment we are in, including family, friends, associates and media in all forms. The more we associate with a particular set of thinking then that thinking expresses itself in our actions manifesting in the body, mind, and spirit. The first man fell because of being influenced by a disobedience spirit and God's first order of business to start redemption is to separate Abram from his unrighteous associations.
