Our Dual Nature- Question

In my last study I examined how God gives us laws so that we may receive blessings and grow spiritually. But then we require a Savior to save us, because inevitably we end up breaking those laws instead. It frankly seems like a very roundabout way of doing things, which would suggest that there is more to the story.

Our problem, of course, comes from the fact that there is a good part to our nature (the spiritual), and a bad part (the carnal). If we just didn’t have this carnal side, then it seems like everything would be solved! We wouldn’t be swayed by temptation, we could effortlessly keep all of God’s laws, and we wouldn’t require saving.

So a few questions naturally arise. Why do we have this carnal side to us then? What is God’s reasoning behind raising imperfect children who require a Savior to rescue them? How does this all fit into His plan?
