I was being too wordy because I spent a long time explaining what contentment is, what it takes to be content and some things that can rob us of contentment. But honestly, most of us know all of that. So today is going to be short and sweet.
You know that you are more fortunate than most people in this world simply because of where you were born. If you are a Christian, you know what a great thing you have waiting for you after this life is over. If you are not a Christian, you know that whenever you are willing, you have something greater waiting for you.
There are times that it's okay to be sad, upset, or want more for yourself, but on a deeper level if you still feel as though you can't be happy and content with what you have, then you just need to do some serious soul searching and figure out why God alone isn't enough for you.
Your life was never intended to be perfect. If it was, there would be no need for you to want something more. Stop searching for the perfect relationship, the perfect job, the perfect kids, the perfect home, the perfect clean bill of health, or the perfect financial situation. They don't exist, and if they did they still wouldn't bring you true contentment.
Start searching to do everything (and I mean everything) to God's glory and not your own. If you do this, I guarantee you that you will not be stressed and worried all the time, but you will find you're closer to the ideal situation that you're searching for anyway.
This lesson took me a very long time to learn but I do think that I am doing relatively well at being happy with what I have.
If you are having a hard time with being content, I would say to first just pray and ask God to help you to be content. And then just go out and start serving other people. If you focus on others, God will focus on you.
"Godliness with contentment is great gain." 1 Tim. 6:6
