By faith we understand. The seat of faith is not the understanding or the reason, but the heart. Once faith possesses and quickens the heart, it then acts through the understanding. Faith understands divine things; through faith we can have spiritual understanding. If our faith is to worship and work properly, it must truly learn this first lesson: the created order (Rom1:20), instead of being a veil which hides God, can become to us transparent with the light of his presence.
