Years ago I found myself with an extra sum of money during District Convention season for our area. Knowing we had a few in our congregation that were struggling, I approached an elder and asked if there was a fund in place that was used for helping local brothers get to the convention city or pay for lodging, etc... I got such a look of suspicion and it almost seemed like his face went into slow motion.... "Whyyyyy...?", he asked.
I quickly put it together that he thought _ I _ was asking for money and he was extremely uncomfortable with it. That made ME extremely uncomfortable so I quickly added, "I just wanted to pitch in to help the LOCAL brothers but I don't know what the arrangement is."
I gleaned from that experience that charitable giving is not a comfortable arrangement or topic inside "God's Christian congregation."
