God gives some people the ability to enjoy the wealth and property he gives them, as well as the ability to accept their state in life and enjoy their work. They do not worry about how short life is, because God keeps them busy with what they love to do.
Ecclesiastes 5:19-20 (NCV)
Be glad and generous with what God has given. Take pleasure in the work you have been called to. Having a cheerful heart and attitude is a great blessing and eases our burdens.
