Modern people think that they know how everything works and do not find God in any of it. Post-moderns do not care how anything works—as long as the battery is charged. Both philosophies discard any idea of general revelation, which is God showing his power and nature to humanity.
I believe that God’s reveals his existence and purposes in such things as physical reality, history, and human nature. Paul wrote that nobody had any excuse for not acknowledging the existence of God because of what was revealed to us in his creation of physical reality. The Old Testament shows God working in human history to show us what we are to do collectively as members of nations. God reveals his framework for human communities by providing everyone (with a few possible exceptions) a sense of right and wrong.
Any or all of these three aspects of general revelation can be denied or ignored by individuals and/or societies. Proverbs 1:20-33 describes this very situation. Wisdom (God’s voice) calls out in public places and is rejected by people given various derogatory names by the writer of Proverbs. These will suffer great harm because of their foolishness. At the end of the passage, a blessing is pronounced on those who listen.
Sometime time ago Time magazine had a cover which asked the question, “Is God Dead?” The April 3, 2017 issue asks “Is Truth Dead?” I believe there is an inevitable trajectory between those two issues. A society that pushes God away cannot maintain its hold on truth. After all Jesus told us that he is truth and people who reject him are not only turning against him but all the blessings that come with belief in him.
General revelation is a great blessing to humanity but it is not sufficient to bring people to righteousness. People are given the ability to blind themselves to any learning from general revelation and to make their selves deaf to the voice of God, which is one aspect of special revelation. The possession of these abilities does not excuse them for making use of them to refuse to seek and obey God.
