Ecclesiastes 1:4 A generation goes, and a generation comes, but the earth remains forever.
Much of what is said in Ecclesiastes is obvious. What he observed then was limited. His view of the world was limited. Now we have satellites in space exploring every inch of our planet.
As long as man has been an explorer there will always be places we have not gone and life forces that are still mysterious to us. We don’t know what we don’t know.
Isaiah 6:9 And he said, “Go, and say to this people: “‘Keep on hearing, but do not understand; keep on seeing, but do not perceive.’
Observation is merely perception from a personal advantage point.
Isaiah 55:8 For my thoughts are not your thoughts, neither are your ways my ways, declares the Lord.
If we want to see things His way, then we need to seek Him and ask.
Ecclesiastes 6:10 Whatever has come to be has already been named, and it is known what man is, and that he is not able to dispute with one stronger than he.
Matthew 6:8 Do not be like them, for your Father knows what you need before you ask him.
God might answer “That is on a need to know basis and you don’t need to know.”
