Psalm 31:15 — "My times are in thy hand" — was written by David when enemies were surrounding him and death felt imminent. The Hebrew word for "times" — ittim — means appointed seasons, moments, the specific instances of a life. David is asserting that each of those moments — including the final one — is held in God's hand, not swept away by accident. This does not explain sudden death. But it names it as something held, not abandoned.
Romans 8:28 is often used as a premature comfort, but Paul's claim is precise: God is working synergistically across all the things — including the sudden, senseless, unresolved ones — toward something good. The Greek verb synergei means cooperative working, multiple inputs being coordinated. God is not passive in the wake of sudden loss. He is working, even where the working is invisible.
