Whether the spiritual joy which proceeds from charity, can be filled?

Objections

Objection 1 : It would seem that the spiritual joy which proceeds from charity cannot be filled. For the more we rejoice in God, the more is our joy in Him filled. But we can never rejoice in Him as much as it is meet that we should rejoice in God, since His goodness which is infinite, surpasses the creature's joy which is finite. Therefore joy in God can never be filled.
Objection 2 : Further, that which is filled cannot be increased. But the joy, even of the blessed, can be increased, since one's joy is greater than another's. Therefore joy in God cannot be filled in a creature.
Objection 3 : Further, comprehension seems to be nothing else than the fulness of knowledge. Now, just as the cognitive power of a creature is finite, so is its appetitive power. Since therefore God cannot be comprehended by any creature, it seems that no creature's joy in God can be filled.
