According to Acts 14:17, common grace is a source of general (or natural) revelation. So even as God gives grace to the world by sending rain and sun, it accumulates the judgement that will be heaped upon the unbeliever. “For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened” (Rom 1:21 ESV). Truely, all men are without excuse.

I remember RC Sproul talking about this topic. He said that if someone asked him that question about the “innocent native” who has never heard the gospel going to hell, he was answer, “No! An innocent person would go straight to heaven! The problem is finding an innocent person.” All men know enough about God from creation for Him to judge them for not worshiping Him. It is amazing to me since I see God’s “fingerprints” all over creation. The order, the laws, the beauty, the cycles, the balance. Why is it that Carl Sagan couldn’t see it? As Calvin said, the “specticals of faith” are required. Praise God that he gave them to me.
