Jude warns us to avoid the ways of Cain, Balaam, and Korah that characterize false teachers—greedy, worshipping on one's own terms, appealing to the masses.
Balaam illustrates the paradox of someone who knows God's will, but willfully and deliberately disobeys, presumptuously thinking he could manipulate or bribe God.
Balaam, motivated by self-interest, believing that the ends justify the means, willing to do anything to get his way, is spiritually inferior to a donkey.
Blinded by greed, Balaam used whatever mental gymnastics necessary to arrive at the answer he wanted. He turned the grace of God into a license for evil.
Pride, the father of all sins, is the source of self-exaltation, self-justification and the despising of authority. It cloaks rebellion in a deceptive appeal.
While most understand the sacrificial theme of Passover, they fail to grasp actively overcoming sin, largely because of the concept of 'free' grace.
