I look back at years I wasted and choices I cannot undo, and the regret sits on me constantly. What am I meant to do with that?

“Say not thou, What is the cause that the former days were better than these? for thou dost not enquire wisely concerning this.”

The Teacher writes for people who romanticise the past, and he calls the question about the former days unwise. He is not banning memory. He is naming a specific trap: a comparison with an imagined earlier life that nobody can act on, and that quietly drains today of anything worth doing. Nostalgia and regret turn out to be close relatives.

“Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound:”

Paul argues that the law made human failure visible rather than fixing it, then lands on a phrase that goes further than most people are comfortable with: where sin abounded, grace abounded much more. He is not making light of the wreckage anyone has caused. He is saying that grace is not rationed in proportion to the damage, and that it is not a fixed supply which eventually runs out.
