The greatest obstacle to discovery is not ignorance; it is the illusion of knowledge.

The pursuit of the Hebrews was idealized and symbolized by light.  “The Lord is my light and my salvation.”  “The people that sat in darkness have seen a great light.”  “This is the light that lighteth every man that comes into the world.”  The pursuit of the Greeks was symbolized by knowledge.  That’s why the Biblical writers say, “These things are written that you might know that you have eternal life.”  For the Hebrews, it was light.  For the Greeks, it was knowledge.  For the Romans, it was glory.  For the Romans, it was glory, the glory of the city of Rome, the glory of the city that wasn’t built in a day.  And here we have it.  The apostle Paul, a Hebrew by birth, a citizen of Rome, living in a Greek city, had to give to them the ideal of his ethic.  And he says this: “God, who caused the light to shine out of darkness, has caused His light to shine in our hearts, to give to us the light of the knowledge of the glory of God in the face of Christ Jesus our Lord.”  For the apostle Paul, the ultimate ethic was not an abstraction, not symbolized merely by light, not merely by knowledge, not merely by glory, but in the very face of our Lord.  “God who caused the light to shine out of darkness has caused his light to shine in our hearts to give to us the light of the knowledge of the glory of God in the face of Christ Jesus our Lord.

No people will tamely surrender their Liberties, nor can any be easily subdued, when knowledge is diffusd and Virtue is preservd. On the Contrary, when People are universally ignorant, and debauchd in their Manners, they will sink under their own weight without the Aid of  foreign Invaders.

The sacrifice required of Abraham in the offering up of Isaac, shows that if a man would attain to the keys of the kingdom of an endless life; he must sacrifice all things. When God offers a blessing or knowledge to a man, and he refuses to receive it, he will be damned. The Israelites prayed that God would speak to Moses and not to them; in consequence of which he cursed them with a carnal law.

The exaltation and happiness of any community, goes hand in hand with the knowledge possessed by the people, when applied to laudable ends;

whereupon we can exclaim like the wise man; righteousness exalteth a nation; for righteousness embraces knowledge and knowledge is power.

One reason to be humble about knowledge is that much of it is subject to change.

Joseph taught the Saints that knowledge was a necessary part of our mortal journey, for “a man is saved no faster than he [gains] knowledge,”  and that “whatever principle of intelligence we attain . . . in this life, it will rise with us in the resurrection.” During challenging times, it is even more important to learn. The Prophet Joseph taught, “Knowledge does away with darkness, [anxiety], and doubt; for these cannot exist where knowledge is.”

“Faith and knowledge require equal effort and commitment. We cannot expect to have faith at the center of our lives if all of our efforts are expended on knowledge, sports, hobbies, making money, or other pursuits.”

"Those who yearn for true spiritual light and knowledge can only find it through the power of the Holy Ghost. The Spirit enlightens and gives understanding of the eternal purpose of life. By the Spirit, Church members know the restored gospel of Jesus Christ is true."

A knowledge of good and evil is the third element of agency. The first is choice, which is obtained by having two or more options. The second is freedom, which is obtained by having different results from the options. Agency is having choice with freedom as is provided by different results, and then having a knowledge of those results.
