What does Proverbs 10:29 mean?

The safest and best path to follow throughout one's life is the way of the Lord (Proverbs 1:7). This is true much as a doctor's advice makes a person more likely to live a long, healthy life, even if accidents or violence can still occur. From an eternal perspective, pursuing God leads to eternal life (John 3:36; 10:28). Those who are "blameless," in this context, are not people who are "sinless." Rather, they are those who choose to honor God with their thoughts and actions, such that other people have no valid criticisms (Proverbs 2:7; Psalm 119:1). This follows the pattern of this part of Proverbs (Proverbs 10:27–28, 30).

However, the same truth that encourages believers predicts destruction for evildoers. The first chapter of Nahum makes these truths clear. This chapter describes the Lord as avenging and wrathful against His adversaries. It asks, "Who can stand before his indignation? Who can endure the heat of his anger?" (Nahum 1:6). However, against the backdrop of God's judgment on evildoers is His goodness and protection for those who take refuge in Him (Nahum 1:7).

Encouraging believers who were experiencing heavy persecution, Peter writes in 1 Peter 3:12–14: "'The eyes of the Lord are on the righteous, and his ears are open to their prayer. But the face of the Lord is against those who do evil.' Now who is there to harm you if you are zealous for what is good? But even if you suffer for righteousness' sake, you will be blessed. Have no fear of them, nor be troubled."
