"Therefore also now, saith the Lord, turn ye even to me with all your heart, and with fasting, and with weeping, and with mourning:"
I don't necessarily think that God wants us to be sad a lot, but I like the idea that emotion is part of the package. Another reminder that we have to be all in with God. We can't be dedicated to him halfway. Today, let's turn to the Lord... Not just a little bit so we can still turn around and go back to Satan if we feel like it... All the way. With our hearts and emotions too, not as a distraction, but as part of the total package of our broken hearts, contrite spirits, and our whole souls. :)
