3rd Nephi 6:14-16

And thus there became a great inequality in all the land, insomuch that the church began to be broken up; yea, insomuch that in the thirtieth year the church was broken up in all the land save it were among a few of the Lamanites which were converted unto the true faith; and they would not depart from it, for they were firm, and steadfast, and immoveable, willing with all diligence to keep the commandments of the Lord. Now the cause of this iniquity of the people was this—Satan had great power, unto the stirring up of the people to do all manner of iniquity, and to the puffing them up with pride, tempting them to seek for power, and authority, and riches, and the vain things of the world. And thus Satan did lead away the hearts of the people to do all manner of iniquity; therefore they had not enjoyed peace but a few years.

What happened to the Lamanites also has happened to mankind today. We have gotten so worried about ourselves and the stuff in our lives that we have walked away from God. Don’t be like that, keep God in the front and don’t worry about earthly problems.
