The letter kills

"Who also made us sufficient as ministers of the new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life." 2 Corinthians 3.6

The abundance of biblical knowledge can give a feeling of well being. If, however, this knowledge is not practiced, it only serves as a witness against you him on the Day of Judgment. The knowledge of the Word sets one free when it is practiced. By practicing it, the Spirit of God works.
Otherwise, what good is to know it? Who in this world knows the Bible better than satan?

Infirmities

"Surely He has borne our griefs and carried our sorrows; yet we esteemed Him stricken, smitten by God, and afflicted." Isaiah 53.4

Those who know the Bible knows that the Lord Jesus has already taken all of  our infirmities and diseases. However, few are those who know how to take possession of this right. To accept it and take it without any fear or concern for medical examinations is a matter of faith that has nothing to do with the senses.

Plant that will be uprooted

"Then His disciples came and said to Him, 'Do You know that the Pharisees were offended when they heard this saying?' But He answered and said, 'every plant which My heavenly Father has not planted will be uprooted." Matthew 15.12-13

The religious hypocrites do not heed the Word that comes out of the mouth of God. They rather listen to and follow their family traditions. Thus, how could they be free if the knowledge of the Word is what sets one free? Such people are seen as strange plants in the Garden of God, and sooner or later, they will be removed.

The letter kills

"...who also made us sufficient as ministers of the new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life." 2 Corinthians 3.6

The true servants of the Holy Spirit of God transmit Spirit to those who are thirsty for the Spirit.
The other "servants" are concerned with imparting empty knowledge of life that imposes deadly burdens. One must be born of the Spirit to have this discernment. 

Knowledge and Practice

"For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places." Ephesians 6:12

If our fight is against spiritual forces of evil, then we must use the spiritual Power of Good to win. Just knowledge of the Word of God is not enough to win, but rather the practice of it.

Corruption

" God looks down from heaven upon the children of men, to see if there are any who understand, who seek God. Every one of them has turned aside; they have together become corrupt; there is none who does good, no, not one. "

Psalm 53:2-3

Humanity is worried about many things, especially knowledge, but does not care about the will of God. But when, through love or hurt, comes to God with heart, mind, and soul -- His return is immediate.

Revelation

“ Let not the wise man glory in his wisdom, let not the mighty man glory in his might, nor let the rich man glory in his riches; But let him who glories glory in this, that he understands and knows Me, that I am the LORD, exercising lovingkindness, judgment, and righteousness in the earth. For in these I delight,” says the LORD."

Jeremiah 9.23

Nothing in this world can be bought through the glory of the practical knowledge of our Lord Jesus. It is a revelation from the Holy Spirit to those who are chosen.

Law of God

"The law of Your mouth is better to me than thousands of coins of gold and silver." Psalms 119:72

Those guided by the counsels of God acquire knowledge, and consequently, riches are also added.

Hear and keep

"Blessed is he who reads and those who hear the words of this prophecy, and keep those things which are written in it; for the time is near."

Revelation 1: 3

The prophetic words aren't just knowledge. They're to be put in practice, otherwise, there's no use in knowing them. In this case, reading, hearing, and keeping the prophecies from Revelations keeping vigilance of your soul's salvation, trusting that these promises will be fulfilled soon.

More precious

"Neither gold nor crystal can equal it, nor can it be exchanged for jewelry of fine gold. No mention shall be made of coral or quartz, for the price of wisdom is above rubies." Job 28:17,18

The fear of God Job had led him to acquire wisdom. Even when he was tested by the fire, he never blasphemed against God. For this reason, He was able to have his family and wealth back in double.

Much knowledge is nothing without wisdom. The atomic bomb inventor had much knowledge, but lacked wisdom.

Advantage

"For the protection of wisdom is like the protection of money, and the advantage of knowledge is that wisdom preserves the life of him who has it." Ecclesiastes 7:12

Wisdom is like riches, and what is important about it is the life you receive through God's direction, as well as joy and peace with all.
