As a supporter of a ministry financially, we have provided support and other items necessary for those that the Lord has called into the minstry. I often think of the song "Thank You for Giving to the Lord" when thinking about this. We will never know on this side of heaven exactly how our support is used to minister to others.
We are able to support not only in dollars and cents, but through events like the Shoe Boxes provided by Samaritan purses. We have helped in blanket drives for overseas as well as items (like toothbrushes, etc.) for the Ukraine. Even as we send a card for missionaries or others who work for the Lord we provided support emotionally. I truly believe the Lord will use any honest effort from cards, money and especially prayer for His glory.
