To some people happiness is based on their financial status. I’m not saying is bad to be happy and enjoy wealth, but when your foundation of happiness is wealth, that’s when it becomes a problem.
You have to be able to acknowledge God as the foundation of all things in your life. Knowing that the joy God gives to the world is not like the one this world offers, for its temporary. God’s joy is eternal and true. When you have Him as the foundation of your life, no matter what situation you find yourself in, you will always know you can count on God, and His joy will give you the peace and strength to endure all things.
So be grateful no matter where you are financially, there is always something to be thankful for.
