"For since the creation of the world God's invisible qualities - His eternal power and divine nature - have been clearly seen, being understood from what has been made, so that men are without excuse."
The Yellow Poplar is only one of God's many many beautiful creations. I believe that the end line of "we are without excuse" tells us that his beauty and "eternal power and divine nature" can be found all around us. taking the text even further it proves to us that he has designed all things for purpose and beauty. It shows His great power of creation. We should never let a day go by when we dont look around at God's beautiful creation and be in awe of his amazing power.
