There are two perspectives on natural revelation, Augustine-Karl Barth. Augustine respected both nature and reason, while Karl Barth rejected all natural theology because God reveals Himself in His world. This view was questioned by Emil Brunner, who believed that Barth had overstated His care. Natural revelation is mentioned in Ps.19; Rom 1:18-32; 2:12-16; Acts 17:27. But Knowledge that the world was created by the Word of God is not an inference based on observation. It is a truth known by faith(Heb. 1:2-3). If natural theology is seen an attempt to lay foundations for an revealed theology, the results will prove disappointing. But there are many styles of natural theology.
