Understanding

"My son, if you receive my words, And treasure my commands within you,
So that you incline your ear to wisdom, And apply your heart to understanding;

Yes, if you cry out for discernment, And lift up your voice for understanding, If you seek her as silver, And search for her as for hidden treasures; Then you will understand the fear of the Lord, And find the knowledge of God.

For the Lord gives wisdom; from His mouth comes knowledge and understanding; He stores up sound wisdom for the upright; He is a shield to those who walk uprightly; He guards the paths of justice, And preserves the way of His saints.Then you will understand righteousness and justice, equity and every good path." Proverbs 2:1-9
