What does Proverbs 30:5 mean?

Agur (Proverbs 30:1) implied that his natural mind could never hope to understand God (Proverbs 30:1–4). Scripture indicates that all people can know certain things about their Creator (Romans 1:18–20; Psalm 19:1). However, we cannot know everything about God simply by observing nature. In this verse, Agur notes that God's Word—His teaching as recorded in Scripture—is the perfect source of those deeper truths. We should respond to God's general revelation by seeking Him more directly (Matthew 7:7–8).

The most important expression of this knowledge is knowing God personally through faith in His Son Jesus (John 14:6). Jesus asked the Father to sanctify believers in truth, and added, "Your word is truth" (John 17:17). Many of the psalms acknowledge the truth of God's Word. For example, Psalm 119:142 notes, "Your righteousness is righteous forever, and your law is true."

Those who rely on God, as He is explained in His own Word, find Him a source of strength and salvation. This verse affirms that God protects those who rely on Him. The Lord is portrayed as a "shield," as mentioned in Psalm 3:3. Genesis 15:1 records God's promise to Abram after Abram refused a reward offered by the king of Sodom. God promised Abram, "Fear not, Abram, I am your shield; your reward shall be very great." This is not a pledge of perfect earthly safety, but a guarantee that God's will cannot be undone (Romans 8:31–39).
