Kyle Strobel, writing in the new book Advancing Trinitarian Theology: Explorations in Constructive Dogmatics (148, 152):
In [Jonathan] Edwards’s conception, God is not so loquacious as he is luminescent. Creation certainly pours forth speech, as the Psalmist declares (Ps 19), but it is written by the effusive overflow of God’s beauty. This speech is seen and not heard (or only heard as it is seen). The visual takes precedence in Edwards’s theology because of his doctrine of God, his understanding of the beatific vision, and its orientation for faith. One day believers will see “face to face” (1 Cor 13:12), so the spiritual sight of faith is the anticipation — through a glass darkly — of God’s beatific glory. …
Edwards ends right where he begins — with a God who is infinite happiness, delight, and joy. God’s life is, as it were, the truly religious life; God’s life is one of affection, delight, and the vision that “happifies.” God is the great contemplative, we can say, captivated with truth divine by consenting in union with Truth itself — the Logos. As Edwards claims, God’s excellency “is the highest theme that ever man, that ever archangels, yes, that ever the man Christ Jesus, entered upon yet; yea, it is that theme which is, to speak after the manner of men, the highest contemplation, and the infinite happiness, of Jehovah himself.”
God’s life serves as the archetype for perfect knowledge and therefore casts knowledge in a specifically affectionate and contemplative mold. This is why religious affection is a central issue for Edwards’s understanding of Christian life, knowledge, and conversion. To know God, one must know him as God knows himself — by gazing upon his perfect image in the affection and beauty of the Spirit.
