Plantinga talks about redemption in the fourth chapter of Engaging God's World. One of the early metaphors that he uses is one of God cloaking with mercy a universe that has grown cold with its own sin. I like this metaphor mostly because it puts the action on God. God has done all of the work and we deserve no credit in the matter. The fact that we say "yes" to God's call does not give us any credit either. This is also a lot of the Reformed beliefs that I have speaking out. I believe that not only did God redeeming of the Universe through Christ on the Cross, but he also does the working in each of our hearts that brings us to him.
The part that stuck out to me was the famous quote by Abraham Kuiper. The idea that there is not one square inch of the universe that God does not claim is something that I think a lot of people forget. First, when most people think of Christs death on the cross, they think only of Earth being saved; but it was the entire cosmos. Second, there are a lot of things in this world that it would be easy to just get rid of and then we would be closer to God. Sex for example has been misused since the fall. It is our job as Christians to do our best to keep it inside of marriage how God wants it. Another example is music. There is a ton of music out there that is not God glorifying. That does not mean, however, that music should be thrown out altogether. It simply means that it has been misused and we need bring it back to how God intended.
