Of course you can use the story at your church service - thatīs an honor!
Pastor and park ranger? Interesting combination! And yet not so surprising :) I think people who spend a lot of time in nature are often very spiritual. I know my favorite place of quieting my mind and reaching within is an old pine forest. I feel always so grateful for the beauty of the world there. Iīm sure you understand what I mean.
Give my best wishes to your congregation - I hope they will enjoy the Dandelion story. True happiness comes from appreciating the small things all around us. Sometimes we just need to look at familiar things with new eyes.
