When you are employed, it’s difficult to see that you are granted with abundant resources, coz you are used to received fixed salary. Hence you can only spent that much. And we tend to continue the limited resources concept with everything that we have: time, smile, kindness to others, and so on.
I believe that in heaven resources are unlimited. But people are not happy because they own everything. They are happy because they can share their lives with others.
So I must believe that God has provided me more than enough, and not to let the idea stick on my head.
