I am not confusing the two at all. Some others on the board are. I should have never brought it up; it seems to be beyond their comprehension.What you are confusing is the distinction between natural light and supernatural light. The natural man is capable of perceiving what God has revealed in nature and in conscience and that is sufficient to understand, violate and be condemned. However, what Paul is speaking about in 1 Corinthians is not natural revelation but special revelation that requires spiritual discernment which no natural man can perceive.
Natural light is that which is revealed in nature.
The testimony I set forth before you is well documented. It is the testimony of Hudson Taylor, who came to Christ through reading a gospel tract. He was unsaved. Now you and Rippon want to make an absolute statement based on an interpretation of 1Cor.2:14 that his testimony is a lie because he was unsaved (a natural man), and cannot understand the things of God. He was reading Scripture--a Scripture tract particularly about the blood of Christ. That is spiritual. According to you and other Calvinists he is still lost today and probably in hell because he never got saved in the first place. The natural man cannot receive spiritual things. He was reading a "spiritual thing" as a natural man. So he was never saved was he???
