Why do I exist?
On his second missionary journey, St. Paul traveled to the center of the ancient city of Athens to start a conversation with the Greeks who lived there. They were an earnestly religious people, and Athens was full of monuments and temples to their gods and goddesses. Their priests taught them that the human race had sprung from stones cast behind them by a man named Deucalion and a woman named Pyrrha.
Paul did not ridicule myths like these, but he began to tell the people about the real origin of the human race. We came from the mind and will of one God, who launched the entire universe into being. “The God who made the world and everything in it is the Lord of heaven and earth and does not live in temples built by human hands. And he is not served by human hands, as if he needed anything. Rather, he himself gives everyone life and breath and everything else” (Acts 17:24,25).
Nobody today believes that Deucalion and Pyrrha populated the earth with stones. Instead, the academic elite in our world embrace and propagate the idea that the human race is the product of random evolution and mutation. Perhaps someday people will sneer at that idea too, realizing that there had to be intelligent design to bring about such brilliantly imagined and engineered living creatures as you and me.
In the meantime, look up to heaven and give thanks to the One who gave you life and breath.
