This chapter reveals part of the reason why Paul wants us to grow in the knowledge of the will of God and of God Himself. It is so that we do not become entangled, confused, and bound by deceptive philosophies and man-made religions that have no eternal value or ultimate authority.
Having seen true religion manifested in Christ, who has subjected all things under His feet, including the philosophies and religions of men, we are to compare all things to His work and His teaching. We are free from the false and often overbearing rule of earthly traditions and systems of thought that would seek to place us under them, because Christ is our head and has “disarmed the rulers and authorities, He made a public display of them, having triumphed over them through Him.”
So we are bound only to listen to His word. Other men’s words cannot constrain us because they do not have ultimate authority.
