When asked how he felt about the world's reaction to his Grandfather's death, Will, who is also a preacher, said: "To be honest, I haven't had much time to process it all.
"Being a grandson, as a family member, my focus has been directed on my family. We saw very little news; we saw very little publications, just because when you're in the middle of it you don't get to process it all."
The world-famous evangelist died on 21st February but Will explained how it wasn't until his grandfather's body was transported from Ashville in North Carolina to Charlotte that he fully appreciated the effect of Rev Billy Graham's passing.
He said: "Along that two and a half hour drive there were people lined up the whole way except for about 10 kilometres - otherwise it was people sitting on the side of the road, sometimes with large, vast numbers of people sitting there. It was very much overwhelming, emotionally for me, to see people pour out their love for my granddaddy."
Graham's body was then laid in honour in the Capitol's rotunda, a rare honour for an apolitical figure.
Will added that seeing the president, vice president and hundreds of others from the legislative and executive branches, as well as Supreme Court members, pay respect in Washington DC "was a very special moment".
"That was very humbling and a bit overwhelming too, to see all those people come," he said.
As the son of Franklin Graham, and a fellow preacher with the Billy Graham Evangelistic Association, he will be travelling to Falkirk in Scotland this summer to continue their work of preaching the Gospel, purely and simply.
Not only did Billy Graham preach in Glasgow in the 1950s, but the family has Scottish roots too.
"I love being in Scotland, not just because it's my native home country, per se, but because we've just seen God do some amazing things in Scotland," he said.
"Just a few years ago I was in Peterhead and we saw God do some amazing things there."
There will be a three day event in Falkirk stadium 15th-17th June which he described as "a wonderful privilege; I'm looking forward to it and just praying that God will do a great and mighty work".
Will asked Christians to pray for him: "I need prayer more than anything else - to help me to preach clearly, and boldly and with urgency. I want to let people know that this is something that they need to do and that Christ came to die for their sins and all they have to do is just receive it and so that's what I want to tell people when I come this June. So, I'm looking forward to it".
He is also running evangelism classes for free to equip people to tell the gospel.
