Gotta disagree with that dear friend!
I've had a VERY unhappy journey of YEARS in a bad marriage & now am basking in the glory of God's gift of total happiness in the form of love, compassion, truth, understanding, sincerity, and kindness.
Personally, I believe longsuffering (unhappy journeys) are our "trial by fire". We may all go through some really BAD times, but we come out stronger people in so very many ways as a direct result of it. Through the fires we emerge as diamonds ... created by the pressures & fires of those hard times in our lives.
