There is a big difference between what you want and what you need. Human wants are insatiable but what we need to be comfortable are few. Therefore the difference between your wants and needs is Contentment.
What is contentment?
Contentment is to be satisfied with few things that are necessary to meet your needs.
Beloved, do you have great needs, or are you discontented because you don't have what you want? Learn to rely on God's promises and power to help you be content. If you always want more, ask God to remove that desire and teach you contentment in every situation. He will supply all your needs, but in a way that He knows best for you.
Contentment is the key to spiritual growth and personal fulfilment. Godliness is when you honour God and centre your life on Him. Contentment is when you are content with what God is doing in your life. Many people have problems by coveting for what they don't need, borrowing and running into debts because they are not content with what they have.
Beloved one great secret to happiness in life is to be contented(satisfied) with what you have and live a life that is well pleasing and acceptable to God. We brought nothing to the world. All the people unnecessarily accumulate will be left behind and nothing will be carried out of the world.
Therefore be contented.
