Their (1st century AD) world was very different from ours (pg. 13 Evangelism in the Early Church by Michael Green)
While there are some differences there are at least two things that remain the same no matter what culture or era one is looking at. 1. people do not change. God made one set of humans and they all possess the same desires, face the same temptations, have the same goals and so on as everyone else who have lived n this planet.
2. Sin and evil do not change. No matter the culture or era evil tempts, deceives, misleads and continues to ruin God’s creation. The sins faced by the ancient world are the same sins we face today. Science, technology , athletics etc., do not change this fact,
This is why we have the Bible and its timeless words for we are facing the same enemy as our ancient ancestors did and the same problems. The bible is for all cultures and all eras, we do not get a revised set of God’s instructions whenever the culture or era changes. God’s words to us, as written in the Bible, apply to all people of all nations, cultures and eras.
