another post inspired by my attempts at studying for a midetrm

I've been studying Microbiology at Ohio State for a few years now, and whenever people ask me what my major is like, I sometimes like to tell them that, "it's like regular biology, but smaller." Now of course that doesn't really help them understand what I study, but they get a good laugh out of it, and then they move on with the rest of the conversation.

However, if I were to give an actual answer to what I've been studying over the last year, I'd probably say something about how my most interesting classes deal with how bacteria, fungus, and viruses attack the human body, and the immune response to those invaders. 

Simply put, the human body has special receptors on cells that can "see" invading pathogens, which are marked by special molecules on the surface of the bacteria/virus/fungus. When they "see" these molecules, they begin to mount the immune response, and hopefully they can eradicate the pathogen from the system. These receptors are good at recognizing signals that are specific only to outside invaders, and in a healthy human being, will not detect molecules that are on the surface of other host cells. The body can distinguish between "good" signals from "bad" signals.

Now you may be asking, if the body can see "bad" molecules, how come people still get sick and die?  

Well, I'm glad you asked!

One of the strategies that pathogens have developed to combat the immune system is something called mimicry. And it means exactly what it sounds like. Simply put, the bad molecules disguise themselves as host molecules so that they can go undetected by the initial lines of defense of the immune system. Once they get past the front lines, they start wreaking havoc on your body, and if the body can't adjust, well, bad things can happen to you.

Much in the same way a virus can enter the human body undetected, so does sin.

Yeah it's easy to call out sin when it's obvious. Most people know the ten commandments, the go to list of things that make God angry.

Don't lie? Committing adultery? Why would anyone do that? Put God first and don't have idols? Well God gave us these commandments so I should probably follow them. Following these rules can't be too hard... right?

Except of course we make exceptions all the time.

Maybe I'll just stretch the truth a little bit, just this one time, so I don't get in trouble or make this person upset.

I'm not going to commit adultery, heck I'm not even married. But hey, I'm a sexual being. You can't fault me for being a just a regular guy (or girl) with hormones.

Yeah God is great and all, but he'd want me to enjoy all this money, this big house, this giant TV, this great job right? 

This is how sin infiltrates our lives. They put on the mask of rationalization. But why lie to a friend when true friends can be honest with one another? Doesn't Jesus make it clear in Matthew 5:28 when he says, "But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart."? How easily do we fill our time with the pleasures that money can buy, that we forget to worship and look to God for ultimate fulfillment and satisfaction. I'm not saying wealth is a bad thing, but at the end of the day, are you putting your hope a God who never fails, or the mercy of a bank account and an unstable economy?

See, we rationalize all these ideas in our lives, and when our sin is finally exposed for what it is by the Holy Spirit, we have a tough time letting go of bad habits. The disease of sin so firmly entrenched in our lives, it's incredibly difficult to remove it.

Yes, Jesus is the answer, the cure to this disease. He is the God who heals us. But will we continue and listen to what Jesus is telling us? Calling out sin for what it is, not allowing it to slip by our defenses. We must, "put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires," (Romamns 13:14). We don't conquer sin or grow in our walks by going about sinning with no heart for repentance, and then come back to God saying, forgive me. Rather, we look at the world through the eyes of Christ, identifying the sin in our lives, turning away from the path that leads to death and destruction. And when we lose sight, we are all the more reminded of why we needed Jesus in the first place.

Because ultimately at the end of the day, our hearts and our flesh will fail, but our God never will.
