The reasons for this persistent segregation are many: the momentum of history, the locations where worship happens (often influenced, even mandated, by race), differences in comfort zones, and, yes, sometimes, racism.
But I pray that one day Christian congregations will mirror heaven and the words of a song many of us learned as children in Sunday School:
Jesus loves the little childrenEven now, Lord Jesus, "Thy kingdom com, Thy will be done on earth as it is in heaven." Amen
All the children of the world
Red and yellow, black and white,
All are precious in His sight
Jesus loves the little children of the world!
