Focus on helping others rather than on material things

Alma 4 describes how the members of the Church sinned because they
focused on riches and material things and forgot the poor and needy.
Things became so bad that Alma gave up the judgment seat so he could
devote full-time to teaching the people.

Alma 4, verses 8-10 states:

8 For they saw and beheld with great sorrow that the people of the
church began to be lifted up in the pride of their eyes, and to set
their hearts upon riches and upon the vain things of the world, that
they began to be scornful, one towards another, and they began to
persecute those that did not believe according to their own will and
pleasure.

9 And thus, in this eighth year of the reign of the judges, there
began to be great contentions among the people of the church; yea,
there were envyings, and strife, and malice, and persecutions, and
pride, even to exceed the pride of those who did not belong to the
church of God.

10 And thus ended the eighth year of the reign of the judges; and the
wickedness of the church was a great stumbling-block to those who did
not belong to the church; and thus the church began to fail in its
progress.
