CALGARY -- A memorial table for twin brothers who died in an after-hours joyride down a bobsled track at Canada Olympic Park focuses on the boy's faith and their academic achievement.

"Jesus Loves Nerds" proudly proclaims one poster at the table at Calgary's Centre Street Church.

Medals, a ski helmet, flowers, notes from friends and T-shirts with the images of Prime Minister Justin Trudeau and Abraham Lincoln have been carefully laid out before the funeral for 17-year-old Jordan and Evan Caldwell.

"We are so grateful for the prayers and support that we have received," said Pastor Glenn Nudd, who read a statement on behalf of the Caldwell family. "Thank you for sharing this day with us as we celebrate the lives of our boys and as we say goodbye.

"We miss them so much already, but we know that we will be with them in heaven one day."

Nudd, who leads Rocky Mountain Calvary Chapel, has known the boys since birth and said he has fond memories of them.

"They were full of passion, excellence. They loved God and they loved people."

He said the family's faith is getting them through the ordeal.

"It's everything. They're very sad, but their sadness is buoyed up by their faith in Jesus and knowing that they're going to be together again."

Nudd also remembers the fun side of the two young men, who took great delight when people couldn't tell them apart.

"In fact they had a lot of fun being twins that looked exactly the same," he said with a smile.

"How I got to finally figure out who was who is one of them had a mullet and that was Evan, and Evan decided to get rid of his mullet which was hard on me, because I was back trying to figure out who was who again."

An investigation into the accident last Saturday continues.

Evan and Jordan, along with six friends, snuck onto the bobsled run at WinSport's Canada Olympic Park early in the morning.

They went down the run on a toboggan and hit a gate separating the bobsled and luge tracks, which were used during the 1988 Winter Olympics.

There's been no explanation on what prompted the late night joyride. Many of the survivors remain in hospital.
