Robin Rolls from Christian charity Outlook Trust said that making time for someone can really change a life: "That hour might be the best hour they've had in two or three Christmas'.
"It might be the moment that connects them to God because they think 'goodness me, the Church came alive for me in that hour."
Robin Rolls works with older people and was speaking after the charity Age UK released figures that show three million older people say they fear they will be alone this Christmas.
The charity says families are more geographically scattered than ever before and statistics are showing that more than half a million over 65s are not looking forward to Christmas because it brings back memories of loved ones who have died.
He told Premier's News Hour that Christmas is not always a joyous occasion: "There are people sadly who don't enjoy Christmas, it's a time when they've got difficult memories, it's a time when it's only them, it's a time when they've got noone to share it with."
"We're made to be together, we're made to be in community - God you could argue is community - Father, Son, Holy Spirit, and we're made in that image.
"So spending an hour with someone it can reignite memories, it can built friendships."
