The pursuit of the Hebrews was idealized and symbolized by light. “The Lord is my light and my salvation.” “The people that sat in darkness have seen a great light.” “This is the light that lighteth every man that comes into the world.” The pursuit of the Greeks was symbolized by knowledge. That’s why the Biblical writers say, “These things are written that you might know that you have eternal life.” For the Hebrews, it was light. For the Greeks, it was knowledge. For the Romans, it was glory. For the Romans, it was glory, the glory of the city of Rome, the glory of the city that wasn’t built in a day. And here we have it. The apostle Paul, a Hebrew by birth, a citizen of Rome, living in a Greek city, had to give to them the ideal of his ethic. And he says this: “God, who caused the light to shine out of darkness, has caused His light to shine in our hearts, to give to us the light of the knowledge of the glory of God in the face of Christ Jesus our Lord.” For the apostle Paul, the ultimate ethic was not an abstraction, not symbolized merely by light, not merely by knowledge, not merely by glory, but in the very face of our Lord. “God who caused the light to shine out of darkness has caused his light to shine in our hearts to give to us the light of the knowledge of the glory of God in the face of Christ Jesus our Lord.
