As Solomon goes through the various seasons of life, today he covers warfare:
Ecc 3:3 A time to kill and a time to heal. A time to tear down and a time to build up.
If we look at World War 2, from the late 1930s thru early 1940s, there was no shortage of killing across the world. Only after the Berlin fell was there a short lived peace among the Superpowers, where Germany was built back up through the East and the West. Sadly, that was short lived, and the decades long Cold War ensued, giving us the Korean and Vietnam wars.
Looking back millenniums ago, throughout he Bible across the different Old Testament narratives, man has always been at war.
The unfortunate reality is that man spend more time at war that peace. Dwight Eisenhower warned us against the wartime economy, wars mean money, and ever since World War 2, the United States has never not been involved in some kind of conflict.
It seems like right after the fall of Berlin Wall in 1989, we wasted no time jumping into the Middle East with both feet.
Man in his fallen nature is inherently evil, these never-ending wars prove that, the only cure for that depraved sin that we have, which comes from the curse of Adam, is The Gospel, Christ shows us our sin and gives us regerneate hearts that makes us turn away from that sin that we are all born with.
