I have more insight than all my teachers, for Your testimonies are my meditation.
Psalm 119:99
The term “insight” can be translated as “wisdom,” “understanding,” “prudence,” “success,” etc. Insight, or wisdom, is not necessarily associated with age. People may have lots more life experience, but that does not mean that they are wise.
On the other hand, being young does not mean that you cannot have wisdom. You will certainly have less life experience, but that is not equivalent to having less wisdom.
The psalmist has wisdom because he meditates on the testimonies of God. In other words, the psalmist is not merely a casual reader of Scripture. He reads and studies to understand God’s word. He continues to contemplate the Scriptures throughout the day. The truth of Scripture profoundly impacts the mind of the psalmist and, therefore, his perspective of life.
The result is that the psalmist has more insight than all of those who disregard God’s word or take it lightly. Wisdom comes to those who cherish and delight in God’s word.
Proverbs paints a descriptive picture of how a person can attain godly wisdom.
My son, if you will receive my words and treasure my commandments within you, make your ear attentive to wisdom, incline your heart to understanding; for if you cry for discernment, lift your voice for understanding; if you seek her as silver and search for her as for hidden treasures; then you will discern the fear of the Lord and discover the knowledge of God. For the Lord gives wisdom; from His mouth come knowledge and understanding. He stores up sound wisdom for the upright; He is a shield to those who walk in integrity
Proverbs 2:1–7
