While Jesus did say that His Kingdom "was not of this world" (John 18:36) that doesn't mean that His people are never to be concerned with the issues that surround or disrupt daily life for their fellow human beings. Christ took a personal interest in men and women while He lived on this earth. Wherever He went, He was a "medical missionary" among other types.
We are to go about doing good, even as He did. We are instructed to feed the hungry, clothe the naked, and comfort the sorrowing. Persons impacted by man-made or natural disaster (whether large or small) are opportunities for the Kingdom to be seen in a loving and practical manner.
However, there is no religious requirement for Oly-Comm membership. If you care about people, we are happy to have you working together with us! Our motivation doesn't have to be your motivation. Oly-Comm radio operators are community-service minded individuals who are willing to be helpful when practical needs arise.
