Kierkegaard on God's omnipotence...

"Only omnipotence can withdraw itself at the same time it gives itself away, and this relationship is the very independence of the receiver. God's omnipotence is therefore his goodness. For goodness is to give away completely, but in such a way that by omnipotently taking oneself back one makes the recipient independent.

All finite power makes [a being] dependent; only omnipotence can make [a being] independent, can form from nothing something that has its continuity in itself through the continuous withdrawing of omnipotence. Omnipotence is not ensconced in a relationship to another, for there is no other to which it is comparable--no, it can give without giving up the least of its power, that is, it can make [a being] independent. It is incomprehensible that omnipotence is able not only to create the most impressive of all things--the whole visible world--but is able to create the most frail of all things--a being independent of that very omnipotence.

Omnipotence, which can handle the world so toughly and with such a heavy hand, can also make itself so light that what it has brought into existence receives independence. Only a wretched and worldly conception of the dialectic of power holds that it is greater and greater in proportion to its ability to compel and to make dependent. No, Socrates had a sounder understanding; he knew that the art of power lies precisely in making another free. But in the relationship between individuals this can never be done, even though it needs to be emphasized again and again that this is the highest; only omnipotence can truly succeed in this.

Therefore if a human being had the slightest independent existence over against God (with regard to materia), then God could not make him free. Creation out of nothing is once again the Omnipotent One's expression for being able to make [a being] independent. He to whom I owe absolutely everything, although he still absolutely controls everything, has in fact made me independent. If in creating man God himself lost a little of his power, then precisely what he could not do would be to make a human being independent."
