This is one of my favorite chapters in the Bible. Almost everything Paul writes here, I can relate to on a personal level. This chapter also marks a transition in the book of Romans. Previously, Paul talked alot about sins and how God has dealt with the sins we have committed. In Romans 7, the Holy Spirit elucidates on how to deal with the root cause of our sins: the sinful nature. God doesn't try to mend us or repair us. He know that we're a hopeless cause. Our problem is not one that can be suppressed or circumvented. The problem is our very nature, the sinful nature. We are in a constant battle with the sinful nature. Like Paul says, the good that I want to do I can't do. The bad that I try not to do, I inevitably do. I know that for myself, a huge battle was always in the realm of entertainment. For some reason, God gave me a very addictive personality. When it came to video games or TV series, the moment I get hooked all productivity died. Even when things are busy and I know I should study or work, that temptation in my heart always gets me to play one more level or watch one more show. God's solution is to put us to death and give us a new life. He doesn't repair, he replaces. When I finally got on my knees and offered that portion of my life to God, He completely removed the temptation. Even now I may still occasionally feel the temptation of being addicted, but when I pray, He sets me free.
The beginning few verses have always been curious for me. I really like the analogy of the old and new husband. The way I see it is that the Law was the old husband. He was a very stringent and strict husband who wanted things done his way. He needed the dishes washed a certain way, the furniture cleaned and dusted, and the food cooked just to his liking (aka nothing that chewed the curd or split the hooves). This husband was impossible to please. Try as we might, we always ended up failing. He would stand there and criticize us telling us of all the places we failed. For reconciliation, he wanted an unblemished lamb as a sacrifice. Pretty soon, we get tired and give up trying to please him. Luckily, in our greatest moment of need, God interceded. The solution he chose was to put us to death with Christ. When Christ was resurrected, He gave us a new life and a new husband. This new husband still had the same unreachable standards as the old. Except rather than letting us struggle on our own, He helps us complete our choirs. If there's dishes that needs washing, He'll wash it with us. If there's food that needs cooking, He cooks with us. In this way, although these standards are impossible for people to achieve, nothing is impossible with God. And by His strength, we too can live a life free of sin. It is all by the way of the cross.
