My name is Qiana James and I didn't know Therese personally, but I wanted to give my condolences to her family. I am so sorry to hear of her passing. I was so amazed by all of her contributions to preserving the environment. What accomplishments! What a tremendous loss.
I too have loss love ones in the past and one can feel such a void of not having that person here to talk to and share laughter with. I wanted to share these scriptures that brought me comfort and I know will do the same for her family. John 5:28 shows a real hope of being reunited with your dead loved ones and 1 Corinthians 15:26 calls death "the last enemy" and assures us that it will be "brought to nothing."
I hope these words bring you comfort. Feel free to go to the below link to find out more about the wonderful hope that the Bible outlines for our loved ones that we have lost in death:
