Jn 17:3, Col 2:2-3, 1 Jn 5:20
In the Old Testament, Job confessed that the fear of God was wisdom. (Job 28:28)
Job 28:28 And unto man he said, Behold, the fear of the Lord, that is wisdom; and to depart from evil is understanding.
To believe in Jesus as the Christ is true wisdom and eternal life. (John 17:3, Col 2:2-3, 1 John 5:20)
John 17:3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
Col 2:2 That their hearts might be comforted, being knit together in love, and unto all riches of the full assurance of understanding, to the acknowledgement of the mystery of God, and of the Father, and of Christ; 3 In whom are hid all the treasures of wisdom and knowledge.
1 John 5:20 And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.
