There are many biblical truths that are only known in what I call Bible talk—words and phrases directly taken from the Scriptures. No problem with doing that, the Scriptures are the foundation for our faith being grounded in truth. The problem comes when they are used as if everyone does or should understand them, but no clear understanding is given of these Bible terms, words and phrases. Redemption is one of those terms that gets repeated often, but I wonder if it's understood very well. What is redemption from God's point of view? What does it mean for us as humans?
It's not too hard to find a dictionary definition for redemption, there's plenty of online sources for that. I like looking at things a little more "organically," that is, understanding things from a more natural sense. One way to do this is looking at the biblical context of a word. But this may lead to more Bible talk where words stay hidden in a theological form. For instance, Ephesians 1:7 gives a specific working definition right within its own context. It says that redemption comes "through His blood" and results in "the forgiveness of our trespasses," declaring that it is a work of God's great grace.
