People need a reason to live, and resources for living:
It is not uncommon to find people without a reason for living.
They simply exist until they can bear it no longer, or they
fill their emptiness with meaningless pursuits. Other people
have reasons for living, but no resources for living. Once
they attain to their reason for living they are left disappointed
or strangely empty. Many astronauts in America's space
program experienced this. One of them said his whole life
revolved around the mission to land on the moon. Once
the mission was completed, he experienced a severe depression.
He concluded that the only lasting reason for living had to
be found in God, and so he became a Christian. Two other
astronauts who went on the moon also became believers and
are involved in Christian ministries.

The famed poet William Cowper wrote:
God moves in a mysterious way
His wonders to perform;
He plants His footsteps in the sea,
And rides upon the storm.
His purposes will ripen fast,
Unfolding every hour:
The bud may have a bitter taste,
But sweet will be the flower.
Blind unbelief is sure to err,
And scan His works in vain:
God is His own interpreter,
And He will make it plain.
