What is always equal in heaven?

Here, in heaven, I am reading of ever-fresh proofs of the fatherly love of God, and I also understand my own inner life better and more thoroughly at every fresh observation.

Add together the morning freshness and the evening tranquillity, that vivid morning feeling, which flows through your whole being, and the peaceful evening feeling inspired by the hope of slumber, and then you will have some notion of how we feel in a land where no sun rises or sets, where no midday heat exhausts and unnerves and where the rapturous joy of existence is always equal.
