Who Am I?

That's the question that came into my mind tonight while reflecting on the past few days in Kenya. I never thought four years ago that my heart would be stolen by these children and these loving servants here who look after them, love them and teach them. Who am I to be given the gift to see and feel this kind of love in a place where I never expected to be? There's a line in the song "Who Am I?" by Casting Crowns that says:
"Who am I, that the Bright and Morning Star
Would choose to light the way
For my ever wandering heart."
Every time I come here, I'm amazed at how my hard, frozen, wandering heart can be melted yet again. I've done nothing to deserve this gift. Who am I indeed.
