The film had only one redeeming feature – a snippet of dialogue in which the Archangel Michael informs the Archangel Gabriel that Gabriel gives God what he wants whereas he, Michael, is more interested in providing God with what He needs.
Gabriel gives God what He wants via unfailing obedience. Thus, Gabriel has no reservations or qualms about a disillusioned and wrathful God ordering him and the other angels to descend upon the earth and exterminate humanity. Steadfastly obedient, Gabriel does not pause to reason why God wants to unleash the apocalypse but faithfully adheres to the “whatever God wants, God gets” credo.
Michael, on the other hand, not only questions the rightness of God’s decision; he blatantly chooses to disobey it, guided by the intuition that God’s impulse to destroy humanity might not be what God needs. Michael senses that God needs a restored faith in humanity. Thus, the archangel assumes the risk of disobeying what God supposedly wants to provide God with what He needs.
As terrible as Legion was, this small snippet of dialogue started me thinking about how the matter of God's wants and needs signifies a demarcation line in contemporary Christianity – a perceptible distinction between two broader categories of Christians.
On the one side are Christians who believe it metaphysically impossible for God to have any needs. Within this metaphysical framework, God does not need man or any other created Being. Man and every other created Being needs God.
Since God does not need man or any other created Being, the most God can do is want something from them -- obedience, faith, love, and worship. Although these wants are often expressed or interpreted as needs, they are not truly needs because God is independent in Himself and is sufficient to Himself. Thus, the best man or any other created Being can strive for is to obey God and provide Him with what he wants.
On the other side, you have Christians who sense that God, as a loving parent, has genuine needs beyond mere wants. Such Christians also sense that the core purpose of Creation centers upon aspiring to those needs.
Hence, the purpose of Creation is not mere obedience to what God wants – usually expressed solely through externals like scripture, doctrines, laws, traditions, and rituals – but the active pursuit of discovering and pursuing what God needs, which transcends externals and emanates primarily from the internal.
The wanting God seeks obedience; the needing God seeks creativity.
