In Moses and Abraham's time, God had dictated that certain foods were unclean to eat, and should be avoided as a religious law. I've heard many arguments over time as to why this was, but I like the reasoning most that God was simply trying to protect his people. This was well before the time of refrigeration. And while a side of beef will be fine for several days left out (actually improves with age) a side of pork will not be fine- it will fester and fill with disease.
Anyway (not the point at all today). Jesus made a point to say to his followers that what they eat is not what keeps them away from God. He was questioned on this by Peter, and so he explained: 6
Look at the list of things that Jesus mentions defiles us, murder, adultery, sexual immorality, theft, lying, and slander. When I think about the severity of those... God places a liar in the same place as a murderer. Think about that! If we want to be close to God, we need to keep these things out of our minds and lives. How easy it can be sometimes to tell a lie or two, or in the case of slander- to share a bit of gossip. But when we do that, we are no better than someone who takes a life or sleeps with someone else's wife.
Yesterday we found out that in order to be intimate with God, we need to take the first step and desire to draw closer to him. He will become closer to us, but we need to become closer to him first. Today we find that another step towards intimacy is to cleanse ourselves of unclean thoughts and actions. My Bible calls this step Inner Purity. We have to strive towards inner purity if we want to discover intimacy with God. This looks and sounds easy on paper. But I think to actually achieve inner purity it's going to take a bit of prayer and a bit of work. And a bit of help from God.
