As is true of us all, the paths of these four friends have at times been rocky ​ — whether because of experiencing the pain of losing a mate, the stress of contending with serious illness, the concerns of caring for aged parents, the difficulties of raising a child while in full - time service, the apprehension felt when accepting new theocratic assignments, and now increasingly the problems of old age.
Seperti yang kita semua alami, perjalanan hidup keempat sahabat ini juga tidak selalu mulus. Mereka merasakan pedihnya kehilangan istri, stres sewaktu menghadapi penyakit berat, kekhawatiran dalam mengurus orang tua yang lansia, sulitnya membesarkan anak sambil melayani dalam dinas sepenuh waktu, kekhawatiran sewaktu menerima tugas baru, dan problem - problem akibat umur yang semakin tua.
