We are bombarded with the idea that man has evolved/is evolving and that mankind is greatly more advanced in mind and ability than his (our) ancestors. While I believe the Bible is historically accurate rather than the evolutionary mythology, I think that we can see a parallel in the thinking of young children and earlier generations vs that of more mature people and later generations.
Children tend to think in black and white, concrete terms. While older people have learned to relate to symbolism and even analytical reasoning. I may be way off base, but it struck me that in the Bible’s Old Testament — especially early on — people were more concrete, black and white thinkers. (Of course there is still black and white, good and bad, as well as absolute truth.) As time progressed, the people began to have idols. These were physical objects. Perhaps there was some symbolism to them, but the idols themselves could be seen and touched. Fast forward to today. Our idols may not be physical objects as theirs were, but they are just as detestable. Many of the physical or simple elements we see in the people of Bible times parallel our lives today. Just because we may have “grown up” and left behind the ways we may view as more “primitive” (whether we hold to the evolutionary view or not it is so pervasive in our culture that we may find ourselves thinking along those lines anyway), we should know that we have not outgrown sin or our need for a Savior.
