Proverbs 2:20 “That thou mayest walk in the way of good men, and keep the paths of the righteous."
This is Solomon’s third reason why when wisdom enters into our heart and knowledge is pleasant unto our soul that discretion will preserve us and understanding will keep us (Prov. 2:10-11). The other two reasons why discretion and understanding will keep and preserve us is to deliver us from the way of the evil man and from the strange woman (Prov. 2:12, 16). God delivers believers from sin, to empower us to live unto Him (1 John 1:9).
When God’s wisdom enters a believer’s heart and His knowledge is pleasant to his soul it results in deliverance from evil and the empowerment to do what is right (Romans 6). This deliverance and empowerment to be discreet and have good understanding comes from obeying, crying out and seeking whole heartedly after God’s wisdom (Prov. 2:1-5). Solomon starts out his dissertation to his son on the rewards of wisdom, saying, "My son, if thou wilt receive my words, and hide my commandments with thee…" (Prov. 2:1) God’s wisdom, therefore, starts with a proper relationship with one’s father. God resists the proud and gives grace, the power to do what is right, to the humble (James 4:6, Phil. 2:13). How you honor your dad, will be how you honor your Heavenly Father which in turn will have a huge impact on the rest of your life.
The Hebrew word for walk means to "exercise one self." The Hebrew word for "keep” means "to guard, to hedge about as with thorns, to regard, to observe." God’s purpose for us is to exercise ourselves in the way/lifestyle of the good and follow the Godly examples/paths of the righteous. How do the righteous walk? The Hebrew for "righteous" in this passage is the same Hebrew word for "just" in Habakkuk 2:4.
Habakkuk 2:4 says, "… but the just shall live by his faith.” Thus the paths/example of the just/righteous is to walk by faith. God calls us to a life of doing what is right no matter the cost. Faith believes that God is who He says He is, and that He is rewarder of those who diligently seek Him (Hebrews 11:6). Proverbs 2:21 contains the promise that the upright will dwell in the land and the perfect will remain in it.
Now let’s apply the verse by asking ourselves several questions. "Is discretion and understanding preserving and keeping me because I love and seek God’s wisdom as one would seek silver and hid treasure (Prov. 2:4)? Do I treat my father with due honor and respect and therefore honor my Heavenly Father? Am I walking by faith? Am I exercising myself unto Godliness, that is, training like a disciplined athlete/Olympian? 1 Timothy 4:7-8 "But refuse profane and old wives’ fables, and exercise thyself rather unto godliness. For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come."
