Colossians 2

4 I tell you this so that no one may deceive you by fine-sounding arguments.
We are consistently reminded by Paul how important it is to have a single mind for Christ. The best way for me to possibly do this is not just read but also study in depth the Bible. Human desires and ambition can lead people to distort God given scripture into false doctrine which is more appealing to our thoughts. This can lead us further away from worshiping God and more to glorify our own efforts.

22 These rules, which have to do with things that are all destined to perish with use, are based on merely human commands and teachings.
Legalism is attractive because it can make people seem morally righteous, however only God can change the heart.
