As far as I can reason, an omnipotent God is an impossiblity unless you are willing to embrase a paradox.
Can God create a rock to heavy for him to lift?
This question leads to a paradox. God can not be capable of both feats since they are mutually exclusive.
Some people subscribe to the idea that omnipotence means being able to to everything that is logically possible as opposed to everything at all and, they say, since the above is not logically possible it does not contradict God's omnipotence.
However, this question is actually the combination of two logically possible actions. These being:
1) Creating a rock to large for anyone to lift.
2) Lifting any possible rock.
Therefore a God capable of any logically possible action would be capable of both of these, which again leads to a paradox. Ergo, God can not be omnipotent without also being paradoxical.
