Amazing show of faith, Adam.
I was where you are last year, the youngest of 3 knowing all my life that I was being raised by an AWESOME man. I always used to say that Jesus took notes while watching HIM! He was my hero, too, mostly because he lived his life in a way that showed God's love, not to condemn but to convince!
Your Dad is being greeted by my Dad and Mom in his new home today. I know they'll discuss how proud he is of YOU.
Missing him is human, you loved him and you will have moments of complete dispair. Realize that you will survive this. Because you KNOW what you KNOW.
God bless you and the life of your AWESOME dad....
