I don't think the intention of the song was to illustrate suicide, but moreso a terminally ill loved one who has lost the will to live, someone who has lost the fight. The loved ones around this person are adamantly and sternly attempting to convince him (in this case, John's father) that it's not his time to go and he must be strong. Don't call death and surrender to the mystery of life, and afterlife. "Save the mystery" of what's beyond this life for "another day."
