Good Friday always makes me think about a story a pastor of mine told me. He was just a few years out of seminary and had to visit a church member at the hospital. The church member had just lost their 17 year old son in a car accident. He was the church members only child.
My pastor was as nervous and anxious as he can ever recall being. He knew that there were absolutely no words that would console a grieving father going through a tragedy like that. He was not looking forward to being there and answering a "why" question, especially in this moment. There is no answer that a parent would accept. To make matters worse, he even felt silly having to do it as a mid 20 year old without a family. He felt powerless and had nothing to offer, despite reflecting on it for hours trying to prepare.
When he got to the hospital and met the father, the father broke down in tears. The father struggled to tearfully say "I don't understand…I don't understand how God could willingly sacrifice his only son for us." My pastor said that he just broke down and wept along side of him.
