To be truly human ends up being truly like Jesus, or for those who are redeemed in Jesus, it is being changed into the image of God in Jesus.
Sin renders us less and less human, truly human. Centered in ourselves, turned in on ourselves we end up losing our true selves. When we use other humans we lose what it means to be really human. Rob Bell in Sex God has a helpful chapter on this. This is a part of being turned in on ourselves. Everything is to serve us, even God, if we believe in him.
We are naturally bent on a self-destructing mode; we want our way instead of God's way. Instead we must take the way of Jesus. In doing so, because of Jesus' true humanity, and he taking our falseness so we could take his reality to become like him, we begin to become what we were created in our unique ways to be.
This is neither something we can invent or imagine, or even understand so as to experience just by reading about it. It takes a commitment of faith to an ongoing walk in Jesus together- no less. To be truly human means being in right relationship to God as well as to other human beings, including ourselves, and to the world God has made.
We must shun all false paths, everything the world has to offer, taking only the path found in God in Christ and found in the Story we read in Scripture. We begin then to find our true story as part of the real Story, being truly human because we're in right relationship to God and to others through Jesus.
Just a little sketch on this. What might you add related to this?
