We who are Christ followers are declared by God to be brothers and sisters. There is something very special, even miraculous, about the love we are supposed to have for each other, since we are brothers and sisters.
Gary share's his family's story of how God moved in miraculous ways to create an earthly family with "foreign" children grafted in and how accepting someone who is different can bring great joy and increased love. He then relates that to how members of God's family should relate to each other.
Do we love each other like brothers and sisters?
Do we even know each other?
