My fathers favorite,,he was a gardeners in his spare time, roses he worked on. He used to hum it. He taught the men's bible class at the Methodist Church for fifty years. His grandfather built the oldest Methodist Church west of the Mississsippi,,he was a circuit rider. We have a long tradition of Methodists.
It is a beautiful hymn.
I'm so sorry for your loss. It sounds like he was a wonderful man. You should carry on his tradition of faith. It sounds like it already lives in you . . .
