Introduction
After v. 8 names Noah as a recipient of grace, v. 9 describes the life that grace produced: just, blameless among his peers, and walking with God. Grace is the root; godliness is the fruit.
Historical Context
Original Language Insights
'Perfect' (tamim) — complete, with integrity. Not sinless, but undivided.
'Walked with' (hithallek) — habitual companionship, the stride of an ongoing friendship.
Theological Significance
The order matters: grace first (v. 8), then righteous walking (v. 9). Noah did not earn favor by his godliness; his godliness was the visible shape of favor already received.
Practical Application
Holiness in a corrupt culture is not impossible; it is exactly what Noah did. The secret is companionship: walk close to God, and the world's pull weakens.
