Give me understanding

Psalm 119: 169 - Give we understanding according to your word. 

 The especial work of the Holy Spirit in the illumination of our minds unto the understanding of the Scripture is called "understanding." The Psalmist prays "Give me understanding, and I shall keep thy law" (verse 34). So the apostle speaks to Timothy: "Consider what I say; and the Lord give thee understanding in all things": 2 Timothy 2:7. Besides his own consideration of what was proposed unto him, which includes the due and diligent use of all outward means, it was moreover necessary that God should give him understanding by an inward effectual work of his Spirit, that he might comprehend the things wherein he was instructed. And the desire hereof, as of that without which there can be no saving knowledge of the word, for advantage by it, the Psalmist expresses emphatically, with great fervency of spirit in verse 144: "The righteousness of thy testimony is everlasting: give me understanding, and I shall live." Without this he knew that he could have no benefit by the everlasting righteousness of the testimonies of God. 

All understanding, indeed, however it be abused by the most, is the work and effect of the Holy Ghost for "the inspiration of the Almighty gives understanding": Job 32:8. So is this spiritual understanding in an especial manner the gift of God. In this "understanding" both the ability of our mind and the due exercise of it is included. This one consideration, that the saints of God have with so much earnestness prayed that God would give them understanding as to his mind and will as revealed in the word, with his reiterated promises that he would so do, is of more weight with me than all the disputes of men to the contrary. No farther argument is necessary to prove that men do not understand the mind of God in the Scripture in a due manner, than their supposal and confidence that so they can do without the communication of a spiritual understanding unto them by the Holy Spirit. This self confidence is directly contrary unto the plain, express testimonies of the word. — John Owen.
