They know the joy of giving, sharing, and sacrificing. They know the joy of looking into faces where hope has been renewed, where faith has been restored, where gladness and joy have replaced gloom and misery. They know the joy of deep friendships and rich fellowship. They also know the joy of receiving mercy. Nobody is above need.
Nobody is above needing compassionate response.
Those who show compassion receive compassion. They receive it from those to whom they have shown compassion. But best of all they receive it from the heavenly Father. Their sensitivity to people in need makes the Father in heaven very sensitive to them when they are in need.
