attributes of God: omnipotence

i think that all of God's attributes should be understood in collection with each other. for instance, lets take all-powerful: god can do anything he wants. but because he is also totally good, he cant want somethings, like to do evil. he cant do everything we want him to do because we aren't completely good, nor would he want to. god is also omnipresent, time cannot restrict him because he is outside of it. so now, not only can he not do somethings we want him to, he might not want to because something better might come of it. all knowing also goes hand in hand with omnipresent.
