What are the signs of life?

I have slowly been going through a devotional book by David Jeremiah called "Signs of Life". It is so eye opening and easy to understand. The basic premise of the book is that the Signs of Life for an authentic Christian are dusty shoes, rolled-up sleeves, worn-out knees, outstretched hands, and open arms. It really makes me think about where and how I have been walking. Just today a co-worker of mine brought a situation up in our training class that just screamed out SOMEONE HAS GOT TO DO SOMETHING! Why is it always someone? The discussion led to many possibilities, call a church for help, call adult protective services, just give them a list of community resources. My co-worker said again, I just can't hand them a list of people to call when they can see the sky through their roof! Well she did make some calls, the church said"it is too far for us" (they were in another part of Dallas), adult protective services said "someone will go out and take a look in a week or so", she wasn't satisfied with that either. So she sent out an email which I forwarded to some of you guys and she asked for help, any kind of help. Will anyone be willing , will I be willing? Willing to get my shoes dusty, my sleeves rolled-up, spend some of MY time just for someone else? Someone who doesn't live near me, doesn't look like me, doesn't even know me? There are opportunities all around me every day, how many do I just walk on by or step over, to avoid getting my shoes dusty? I imagine that Jesus' feet were really dusty...
