Alex Nsengimana tells his story to Calvary Christ Church congregation
He held up a comb and a candy cane - they were two small gifts he had received years before.
When he was barely 7 years old and living in an orphanage, Alex Nsengimana of Rwanda received the two items in a decorated shoe box. They were the best possible presents.
The presents were among the thousands sent by people around the world by Samaritan's Purse, which runs Operation Christmas Child.
