Just for sake of a reasonable theological argument:
1) The bible clearly puts limits to what god can do: e.g. He can't lie, He can't break his own laws, etc. in short: The biblical god has some limitations.
However, the biblical god can control the outcome, the result he desires will come to pass.
2) What name would you give the ability to cause whatever you desired as the final result regardless of what anyone else tried to accomplish?
Imagine that: Whatever outcome you desired, regardless of what anyone actively did to try to prevent it, their efforts will be in vain and in fact usually end up causing the outcome that your desired?
The ability to control the result is much more limited then (absolute) omnipotency, but for all desired intents and purposes it is as close as one could reasonably get. I don't think the term omnipotency is meant to be taken as an absolute ability but more as a relative ability so that whatever else happens, god has the ability to control the *end result* regardless of *the path* we decide to follow towards it?
