1. In one account of a near-death experience, the person saw a group of folks with Zeus-like physiques who were playing some kind of game which involved a ball. Where did this ball come from? If humans in paradise acquire a power to simply have things wished for magically appear, then they become equal to the Father who can create ex nihilo. This is impossible; besides, such absolute power would corrupt everyone (but the Father).
(St. Thomas' argument proves this last proposition decisively: "God's power is His goodness: hence He cannot use His power otherwise than well. But it is not so with men. Consequently it is not enough for man's happiness, that he become like God in power, unless he become like Him in goodness also." (ST, II-I, 2, 4, reply 1) But the latter is not possible. Hence, neither is the former, and not even close.)
2. Could those players have asked the Father to create a ball for them? This, too, is grotesque, because humans already have their own power to control the material world. This life is partly about subduing the earth and learning to tame wild nature for our own benefit. The idea that such a major aspect of human existence as mind over matter would just disappear so completely in paradise is difficult to take seriously.
Even worse, we would be dependent on the Father for everything. We'd have to beg Him to give us toothbrushes. But humans are noble and self-sufficient creatures. It is completely unbecoming for us to grovel before God for basketballs.
3. Another possibility is that we won't need any goods at all in paradise. Perhaps life will consist of endless carousing: parties, sex, consuming those nectar and ambrosia (this is really the only way to get food without harming the plants). But I think this would become boring quickly. Everlasting life cannot consist of an endless stream of identical experiences.
4. Finally, perhaps there is no paradise; only heaven, where there is nothing but the Thomistic "contemplation of God seen in His essence." This, however, is a most perverse opinion, because humans are not angels, and they differ from angels precisely in having (and needing) an active life. As such, humans fill a unique niche in the hierarchy of being and essence, and help complete that hierarchy together with the angels.
