Eusebius of Emesa

Scripture says that human life is short and full of trouble, but you belong to the unseen and eternal one. And a thousand years are like a single day, or even like a watch of the night. It is during the fourth watch that those who are entrusted to guard it are divided, and it was during that watch that the Lord came to the holy apostles. If he has spoken this way about a thousand years, it is clear that the lifespan of a man is extremely short. The day of the Lord is like a thousand years, and yet it is undivided. No one lives for a thousand years, but no one has known a full day of the Lord either.

Like a cloak, every body grows old with time. But although it grows old, it will be renewed again by your divine will, O Lord. The heavens will not be destroyed, but rather they will be changed into something better. In the same way our bodies are not destroyed in order to disappear altogether but in order to be renewed in an indestructible state.
