TobyMac is speaking out about the “overwhelming love” he’s felt from fans in the month since his son Truett Foster McKeehan died unexpectedly at the age of 21.

In a post shared to his Instagram and Twitter accounts on Monday, the 55-year-old Christian rapper shared a series of photos from McKeehan’s recent memorial service in Franklin, Tennessee. The powerful images depict the boy’s friends and loved ones carrying his casket. Many were clad in red sweatshirts reading “Shiloh,” in tribute to McKeehan’s rap stage name.
