God glorifies Himself toward the creatures also in two ways: 1. By appealing to…their understanding. 2. In communicating Himself to their hearts, and in their rejoicing and delighting in, and enjoying, the manifestations which He makes of Himself…God is glorified not only by His glory’s being seen, but by its being rejoiced in. When those that see it delight in it, God is more glorified than if they only see it.
– Jonathan Edwards
