Helaman 6

"For behold, the Lord had blessed them so long with the riches of the world that they had not been stirred up to anger, to wars, nor to bloodshed; therefore they began to set their hearts upon their riches; yea, they began to seek to get gain that they might be lifted up one above another; therefore they began to commit secret murders, and to rob and to plunder, that they might get gain" (17).

When you being to be content and expect to be given things, when you forget it was God that blessed you, hearts begin to be set upon things of the world. When that begins to happen, people seek to be raised higher than each other. It destroys the unity of the people.

President Henry B. Eyring said:

“God is forgotten out of vanity. A little prosperity and peace, or even a turn slightly for the better, can bring us feelings of self-sufficiency. We can feel quickly that we are in control of our lives, that the change for the better is our own doing, not that of a God who communicates to us through the still, small voice of the Spirit. Pride creates a noise within us which makes the quiet voice of the Spirit hard to hear. And soon, in our vanity, we no longer even listen for it. We can come quickly to think we don’t need it” ("Prayer").

Don't forget God has blessed you. Always be humble. Be grateful for the things you've been blessed with.
