Our culture programs us to equate happiness to the material pleasures, sexuality and other bodily gratification. Choose the right partner with the right actions to stroke your ego and you'll be happy. Do this activity and you will be happy. Buy these clothes, cars, gadgets, etc, and you will be happy. Marriages are destroyed and families are broken because we look for other people to make us happy and when they don't, we abandon ship and create ripples of unhappiness for others as that ship sinks. How many children are damaged by divorce and fighting because their happiness was secondary to the egos or material needs of their parents? We teach them that other people are expendable if they don't gratify our selfish desires. We teach them that obtaining material things is crucial to finding joy. Pursuing money to gain material goods becomes more important than time rearing children, making memories with spouses, and even proper rest. The idea that happiness comes from "entertainment" leads to time spent in emptiness and immorality, opening the door to more temptation and destruction of the values and people who are truly important There is so much ugliness that tends to accompany the concept that we "deserve" to be happy. Throw in the concept of being entitled to it and a blind eye is turned to the negative until far too much damage is done.
The Bible tells us this, "Godliness with contentment is great gain." and Psalm 144:15b "Happy are the people whose God is the Lord!" Godliness is the key to happiness - and being content, not constantly looking for more and more, but being satisfied is profitable. One way I can see right off the bat that it is profitable is because you aren't striving, striving, striving to have things or a movie-perfect marriage. When you are looking at and truly appreciating the things you have, you can build upon them. Try gratitude. Seek contentment.
Philippians 4:12 - 13 "I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. I can do all this through him who gives me strength."
Hebrews 13:5 "Keep your lives free from the love of money and be content with what you have, because God has said, “Never will I leave you; never will I forsake you.”
Luke 12:15 "Then he said to them, “Watch out! Be on your guard against all kinds of greed; life does not consist in an abundance of possessions.”"
Psalm 37:3-4 3 "Trust in the LORD and do good; dwell in the land and enjoy safe pasture. 4 Take delight in the LORD, and he will give you the desires of your heart."
Matthew 6:33 "But seek first his kingdom and his righteousness, and all these things will be given to you as well."
