Joy is an inner peace which comes from abiding in God’s love. To abide in God’s love we must keep His commandments by loving one another as he has loved us (John 15:9-13). In order to do this we must love and trust him with all our heart. Then our joy will be complete; so that even in the midst of pain and suffering we will have his peace and joy. Happiness, on the other hand is a sense of contentment we feel when pleasing things happen to us. It can therefore disappear very quickly and make life miserable if what pleases us is gone or if unpleasing things happen to us. In addition, our pursuit of happiness can make us selfish; and selfishness will make our heart restless.
