From now on, therefore, we regard no one from a human point of view; even though we once knew Christ from a human point of view, we know him no longer in that way. So if anyone is in Christ, there is a new creation: everything old has passed away; see, everything has become new!
One of the remarkable things that humans beings can do is make quick decisions based on limited information. Our ability to draw from learned experience and extrapolate that into intuition and insight within a new situation generally serves us well. Yet there is danger in it to. Sometimes we need to go back and reconsider an initial response to see if there is something unique and new. We need to learn when to let go of an old way of seeing things.
The ideas that we had about Christ as children changed and developed as we matured. This is part of following Jesus. It’s part of growing up. We learn and grow and change. We see Jesus from our own life stage and perspective. But our life is always changing so we see Jesus with different eyes and attitudes.
Paul encourages the church in Corinth to look at Jesus and themselves from a new point of view. Jesus, in his death and resurrection has brought about a new creation. We are part of that. We are made new. We no longer need the old and can let it pass away.
