Yes. God brings things into being from nothing because if God did only act from something presupposed, it would follow that the thing presupposed would not be caused by Him.
Nothing can be, unless it is from God, Who is the universal cause of all being.
Creation is not change, except according to a mode of understanding. For change means that the same something should be different now from what it was previously. Sometimes, indeed, the same actual thing is different now from what it was before, as in motion according to quantity, quality and place; but sometimes it is the same being only in potentiality, as in substantial change, the subject of which is matter. But in creation, by which the whole substance of a thing is produced, the same thing can be taken as different now and before only according to our way of understanding, so that a thing is understood as first not existing at all, and afterwards as existing. But as action and passion coincide as to the substance of motion, and differ only according to diverse relations (Phys. iii), it must follow that when motion is withdrawn, only diverse relations remain in the Creator and in the creature. But because the mode of signification follows the mode of understanding as was said above (Q13, A1), creation is signified by mode of change; and on this account it is said that to create is to make something from nothing. And yet "to make" and "to be made" are more suitable expressions here than "to change" and "to be changed," because "to make" and "to be made" import a relation of cause to the effect, and of effect to the cause, and imply change only as a consequence.
