Grace comes free of charge to people who do not deserve it and I am one of those people... Now I am trying in my own small way to pipe the tune of grace. I do so because I know, more surely than I know anything, that any pang of healing or forgiveness or goodness I have ever felt comes solely from the grace of God.
On a small scale, person-to-person, Jesus encountered the kinds of suffering common to all of us. And how did he respond? Avoiding philosophical theories and theological lessons, he reached out with healing and compassion. He forgave sin, healed the afflicted, cast out evil, and even overcame death.
True healing, of deep connective tissue, takes place in community. Where is God when it hurts? Where God's people are.
We respond to healing grace by giving it away.
