Proverbs 2:7 He layeth up sound wisdom for the righteous: he is a buckler to them that walk up rightly.
The conditional promise continues on the condition of seeking after knowledge. “If you cry after knowledge and understanding and seek her as a treasure, then you will be closer to being “the righteous” and to walking “uprightly.” To those people the Lord lays up sound wisdom and He is buckler to them.
There is a blessing to being accounted righteous and then living according to the righteousness we have been given by grace. It is more than just pleasing God and being accepted by Him; it is having wisdom and a protective shield (the Lord is our shield). When we put on the spiritual armor we take up the shield of faith to quench the flaming darts of the evil one. We walk uprightly when we walk by faith. He is our shield and we are safe, delivered from evil.
Jesus is the wisdom of God, who is laid up for us. Believe these twin truths: we are not as wise as we think we are: the Fall into Sin has made us stupid; we are wiser than we think we are for we have God’s spirit, God’s life, and God’s wisdom within us. It doesn’t get any better than that! “Trust in the Lord with all thy heart, and lean not on thine own understanding.” Without God, our understanding is faulty.
The desire for wisdom is an inbred desire in every human ever since Eve: “the tree was to be desired to make one wise. [Genesis 3:6]” This is the deceit and lure of the “world.” Instead, we may eat of the other tree, the Tree of Life, which is Jesus. Then we have the desire fulfilled. Believe the promise: you are wise, if you look to the right tree.
