We often equate Christianity with suffering -- and there is a great deal of truth in that. But we forget that God created to have a desire to enjoy life -- to experience pleasure (define as a feeling of happy satisfaction and enjoyment). God gave us the capacity to experience happiness, pleasure, satisfaction in life and He wants us to do just that.
In fact, in Ecclesiastes 9 in the message in the midst of Solomon's not-always-very-positive thoughts, he says that God takes pleasure in our pleasure and that each day is God's gift.
I encourage you to think of one thing today that gives you pleasure and embrace doing that one thing with gusto -- knowing that God will take pleasure in your pleasure.
And while you're at it, sing a happy song. Hope this gets stuck in your head all day long!
