Help the Hong family visit their dad

Hi, my name is Raymond and I'm raising money for my brothers family (Denny Hong, Jayeon Hwang, David, Abigail and Sophia) to visit my dad (Benson Hong). Dad is transitioning to hospice care, and is suffering from stage 4 cancer. They are currently serving as missionaries in Kenya at Kendu Adventist Hospital. Since it's peak season the costs of airfare are quite expensive so we are asking for some help so they can see him one last time. Any donation would be greatly appreciated. God Bless! Thank you!
