The son of the Toronto-area pastor who served more than two years of a life sentence with hard labour in North Korea for anti-state activities says his father will worship with his congregation on Sunday morning, following a day of rest and reunion with his family.

鈥淚t was surreal from the beginning to witness my father coming off an airplane after two-and-a-half years,鈥 James Lim told reporters at a press conference on Saturday. 鈥淗is faith has grown stronger.鈥

Hyeon Soo Lim, 62, landed in Ontario on Saturday morning, according to the family鈥檚 spokesperson Lisa Pak. He had not seen his relatives in person since his 2015 arrest on a missionary trip where he is said to have been mainly working to improve food security within the insular communist state.

North Korean authorities freed Hyeon Soo Lim earlier this week. A six-member Canadian diplomatic envoy travelled to Pyongyang to help secure his release.

James Lim said his father first embraced his mother, and then went straight towards his infant granddaughter, who was born while he was imprisoned, when the family was reunited.

鈥淚t was just incredible. Just to see two people that I love more than anybody else in the world finally meet and embrace,鈥 James Lim said. 鈥淵ou play in your head many times what that moment is going to be like. It鈥檚 far greater than anything you could have imagined.鈥

Pak said the family still does not know why North Korean authorities released Hyeon Soo Lim, or what led to his arrest. She estimates the pastor travelled to the country over 110 times to do similar work over the course of two decades.

鈥淢y best guess is that they were concerned about his health, and so they released him,鈥 Pak said.

James Lim said the family relied heavily on their Christian values and never gave up hope during Hyeon Soo Lim鈥檚 imprisonment. He said watching his father鈥檚 taped confession on North Korean state television and the death of U.S. university student Otto Warmbier tested the family鈥檚 faith.

Warmbier spent 17 months in a North Korean prison for allegedly taking a propaganda poster. He fell into a coma, and was medically evacuated to the U.S. on June 13. Warmbier died days later.

鈥淭he thing that we were really concerned about was the terrible and unfortunate passing of Otto Warmbier. That was unprecedented,鈥 James Lim said. 鈥淭hat placed a huge amount of not only burden, but urgency to push the government.鈥

James Lim said his father is grateful to Canadian officials for their efforts to bring him home, adding that he is generally in good spirit and health. He said he is probably looking forward to returning to his typically Canadian pleasures; coffee, doughnuts, and ice fishing.

鈥淗e is so happy to be home,鈥 James Lim said. 鈥淚 think now more than ever, he has never felt more Canadian.鈥

鈥楢 man on a mission鈥

Pastor Minho Song of the Young Nak Korean Presbyterian Church of Toronto describes Hyeon Soo Lim as 鈥渁 man on a mission鈥 who would stop at nothing to help North Korea鈥檚 poor.

鈥淥nce he sets his mind on something, he will go no matter what the cost,鈥 Song told 麻豆影视 Channel on Saturday. 鈥淗e really loves the people of North Korea, especially those who are marginalized and those who are poor.鈥

Song said his friend and fellow pastor worked tirelessly for many years, dividing his time between Canada and North Korea with remarkable energy.

鈥淗e would preach on Sunday and then he would take the evening flight to North Korea . . . he would come back Friday or Saturday in time to preach and look after his flock,鈥 he said.

James Lim said his family has always put the needs of everyday North Koreans ahead of their distaste for the Kim dynasty鈥檚 brutality.

鈥淥ur family鈥檚 position is that we should never forget about the people of North Korea,鈥 he said.

Asked if his father will ever return to the country, he said 鈥渘ot in this lifetime.鈥
