Entertaining Angels or just a con-man

Our church is in a very poor part of town. We always get people coming in (almost daily) to ask for food, money, or just basic help. Yesterday at about 8:00am in the first service a couple with a 4 year old son wondered into our church. The dad came to me declaring that it was his time to submit to Jesus and be born-again. His exact words were, "I came here today to proclaim that I want to be saved." Now what I found particularly disturbing about this is the fact that he wanted to come to our church building to be saved. As if our church carpet has extra Jesus fibers to save people. If you have seen our building you will know that there is nothing godly about this building. In fact it's awfully ugly. I highly doubt the architect was a persevering saint. Upon explaining that he wanted to be saved he fell to his knees at my feet and started to cry. His wife started to screaming "Praise Jesus" and dancing. I quietly reminded them of our open but cautious stance on the gifts and asked them to follow me to my office.

In my office they told me that they left their apartment because they feared for their lives (I believed this). They told me the sad story of their life for the last year and I honestly believed them. What I was unsure of was their motive. I told them they needed to hear the word and they assured me that this is what they wanted and nothing else.

After I was done praying with them the wife told me she was excited to get into our service that morning. The husband looked at her and said "But baby I am so hungry." She said I am hungry for the word. He said but baby I need food. After a few more minutes of their arguing I said "you need money for breakfast don't you?" He eagerly looked at me (with a look of mission accomplished) and said yes. I gave them some cash from the church and they never came back to the other three services we had that day.

Honestly, if this couple came to me and said, "We hate your church" and "We just want some food to fill our bellies" I would have been more eager to give them money. I struggle to know what to do in these situations. I try to always land on the side of helping not knowing for sure whether I am helping a con artist (who needs Jesus) or a saint (who needs Jesus).
