That is a good point!
Have you seen that cute Christian comment on a bumper sticker that reads the Lord's words: "I never said it would be easy, I only said it would be worth it!" ?
Are you familiar with that major condition of salvation which reads: And ye shall be hated of all men for my name's sake: but he that endureth to the end shall be saved?
(New Testament | Matthew10:22)
How about being stretched to your capacity with temptation?
There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able;.....(New Testament | 1 Corinthians10:13)
Living the life that God has designed for us is no bowl of cherries. It can get quite hot!
And I will bring the third part through the fire, and will refine them as silver is refined, and will try them as gold is tried: ...
(Old Testament | Zechariah13:9)
Are there any other clues as to what can cause a great deal of stress, even depression in the life of a person living the fullnes of a Christian life?
I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.
Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life.
(New Testament | Revelation2:9 - 10)
There is alot of pressure in being a Mormon. I suppose that if our faith were stronger, we might handle the stress without depression, but how does one develop faith? By overcoming the trials that God sends our way.
My people must be tried in all things, that they may be prepared to receive the glory that I have for them, even the glory of Zion; and he that will not bear chastisement is not worthy of my kingdom.
(Doctrine and Covenants | Section136:31)
He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death.
(New Testament | Revelation2:11)
What about the lower divorce rate in Utah! Do you think that LDS people have perfect marriages? Or when troubles arise, do they stick it out instead of bailing out?
I do not prescribe anti-depressants as a solution, but you are correct that it does indicate something is different among the LDS.
