The Belgic Confession

Article 2. About the Knowledge of God

Moreover, we know God by two means, first, by the creation, preservation, and government of this whole world. For it is before our eyes as a most beautiful Book in which all creatures, from the least to the greatest, are as certain letters and marks through which the invisible things of God can be examined and understood, certainly His eternal power and His divinity as the Apostle Paul says in Romans 1:20. This knowledge is sufficient for convicting any given people and rendering them inexcusable. But He also bears His very self to us, much more clearly and openly, in His holy and divine Word; indeed, as much as is expedient in this life for His glory and for the salvation of His own people. Psalm 19; Ephes. 4:6; 2 Cor. 2:6.
