" '21 years' is a song I wrote about the recent passing of my firstborn son, Truett Foster McKeehan," he says about this most personal song. "I loved him with all my heart. Until something in life hits you this hard, you never know how you will handle it. I am thankful that I have been surrounded by love, starting with God’s and extending to community near and far that have walked with us and carried us every day. Writing this song felt like an honest confession of the questions, pain, anger, doubt, mercy, and promise that describes the journey I’m probably only beginning. The rest is yet to come. One thing I know is that I am not alone. God didn’t promise us a life of no pain or even tragic death, but He did promise He would never leave us or forsake us. And I’m holding dearly to that promise for my son as well as myself."
