I would like to see us all come together in praising God for the amazing evolutionary processes he wisely chose for his creation—to diversify life on earth and to adapt organisms to virtually every kind of environment. It is mind-blowing and awe-inspiring everywhere we look! Learning about evolutionary processes has been a faith-building experience for many, a huge incentive to greater worship of the creator, YHWH God.
