This inner life that God lives, in the happy land of the Trinity above all worlds, is a livelier life than any other life. We know about it because we have overheard Father, Son, and Holy Spirit talking amongst themselves with the intent that we overhear them and be brought into the conversation. Simply knowing that the life of God in itself is the liveliest of all lives is a medicinal correction to our sick, self-centered thinking….
The crucial thing is that we should rejoice in it. The knowledge that God enjoys perfect blessedness is a great thing. Even if it stays a kind of secret at the back of our minds, as something that we cannot say much about, it nevertheless exerts a tremendous gravitational pull on the rest of our thoughts and affections. Thomas Traherne said, “I have found that things unknown have a secret influence on the soul, and like the centre of the earth unseen violently attract it.”
