For easy reference, NIV:
34 "Then the King will say to those on his right, 'Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world.
35 For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in,
36 I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.'
37 "Then the righteous will answer him, 'Lord, when did we see you hungry and feed you, or thirsty and give you something to drink?
38 When did we see you a stranger and invite you in, or needing clothes and clothe you?
39 When did we see you sick or in prison and go to visit you?'
40 "The King will reply, 'Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.'
Austin, TX has a huge homeless population. Nice weather and liberal government policies causes them to show up and stay.
There's a local organization that's setup a begging rotation and, every morning, buses people from various homeless camps to intersections so they can stand out with their "25¢ Please anything helps" cardboard signs. I don't think that's actually helping; just enabling them.
Normally, I just ignore them. Sure, I'll chat with one if they come up to me while I'm taking a walk, but don't go out of my way and don't give them money. The few I've talked with have had serious mental problems; no way those guys could hold down a job even if you handed them $50k to get started.
I feel like I should do something, but with the scale of the problem there's nothing I can really do that will help (and not bankrupt me). There's some woods 1000 feet from my house that has a few homeless living in it. 1000 feet beyond that there are usually 3-4 homeless guys sleeping on the Jack-In-The-Box lawn. Cross the frontage road behind Jack-In-The-Box and you'll find 2-3 guys sleeping under the highway overpass, and during the day there will be at least 4 guys at that highway intersection begging for money. There's two more intersections between me and the offices that will always have 4 guys begging.
If I handed every beggar I see $5, it would probably cost me around $1000/month (rough math). I can't afford that and I'm not sure it would really help them anyways.
