The purpose of the gospel of Jesus Christ is not to make it possible for you to “be happy”.

We equate heaven with happiness,  and we equate living the gospel of Jesus Christ with happiness.   

Certainly, living in the presence of God, when all is said and done, is a state of light and love. And surely, our lives, when we understand and live His gospel, are better in terms of inner peace and moments of joy than when we don’t understand it or live it.  But the purpose or result of the gospel of Jesus Christ is definitely not to make you happy every day as you work with Him.  If we believe that happiness to supposed to be the ongoing, predictable result of our earnest discipleship we will be disappointed, because, frankly, it isn’t.

Witness:

Jesus was “a man of sorrows and acquainted with grief” and suffered hunger, thirst, fatigue, temptations and pain. (a)

Ammon was “depressed” in spirit and “suffered many things”. (b)

Alma was “weighed down with sorrow”. (c)

Nephi was “much cast down”. (d)

Paul experienced “distress” and “anguish of heart”. (e)

The purpose of the gospel of Jesus is not to make us happy now and every day (though there are moments of happiness in discipleship).  The purpose of the gospel in this life, and beyond, is to change us from a natural man or woman to a saint. (f)

And that change is unlikely if we do not have the opportunity to become people who respond with faith in Christ and love of God, repentance, and openhearted charity towards others, even while simultaneously experiencing all of the above feelings and challenges as we engage in the work of disciples of Christ.
