It’s not happiness that makes us grateful, but gratefulness that makes us happy. (David Steindl-Rast, author and lecturer)
Apparently, a lot of people have not made the connection that Steindl-Rast speaks of. Everybody wants to be happy, and hosts of people are seeking joy and contentment in all kinds of places and associations. Discontent and dissatisfaction seem to go with always wanting more. Thankfulness for what you have and gratitude to those who provide it will help bring joy and pleasure.
Since everything God created is good, we should not reject any of it but receive it with thanks (1 Timothy 4:4).
