Everything on earth loses value as time goes by. As the book of 2 Corinthians chapter 4 verse 16 says that, "Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day." All the things in our houses lose value the minute we exit the store we bought the product. Just like a car the minute I leave the dealership the car loses value. Even our bodies are wasting away as we grow and we are going to be seen as less consumer value to the society around us. This does not apply to God. The Bible teaches us that exact opposite happens in His presence. Day by day we grow substantially in wisdom and spiritual knowledge.
