As I drove in this morning, I drove through many conversations that I did not see, nor did I hear. I did see the cell towers and guessed that they were in use. I even wondered if more people were talking on their phones or if more people were praying.
2 Corinthians 4:18 (ESV)
18 as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.
