A Cosmological Argument for the Existence of the One

This is a post similar to one I did earlier, except this one simplifies the argument:

1. If A and B are causally related, then A and B have something in common.  (Premise)

2. Everything that stands in causal relations possibly has the ability to causally influence every other causal power.  (Premise)

3. Hence, everything that stands in causal relations has something in common N.  (From 1 and 3)

4. N is either temporally contingent or temporally necessary.  (Definition)

5. Every moment of time stands in a causal relation.  (Premise)

6. Hence, N exists at all moments of time.  (From 3, 4 and 5)

7. Therefore, N is temporally necessary.  (From 4 and 6)

N's eternality may be deduced by the fact that N cannot fail to exist at any time.  N's tremendous power may be inferred by its ability to sustain all causally potent entities.  The fact that all causally potent entities have this in common, rather than in distinction, points to N's unicity.  Therefore, an entity exists which is temporally necessary, eternal, very powerful and unique: this is the One, or God.
