No doubt all right to existence, to immortality, to felicity of any kind, is derived from God, and is originally a free gift to the creature from him. But the right is a real right, of which the creature has just possession when God has given it to him, one which may be an inalienable right in certain circumstances, that is, a right which God cannot, in consistency with his own attributes, withdraw. When God creates a rational nature, in which he has implanted the desire and expectation of immortal existence and felicity, he implicitly promises immortality and felicity. We do not like to hear it said that he can annihilate such a creature or withhold from it the felicity after which it naturally aspires, unless it be as a just punishment for sin. {128} So, when God creates man anew in the supernatural order, by giving him the grace of regeneration, he gives him an implicit promise of eternal beatitude. It is very true that he can exact from him any amount of service he pleases, as a debt that is due to his sovereign majesty; yet he cannot justly withhold from him final beatitude, unless he forfeits it by his own fault. The special reward annexed to every good work is undoubtedly due only by virtue of the explicit promise which God has made, to reward every such good work by an increase of grace and glory. It is also true that God does confer some degrees of glory on the just out of pure liberality and beyond the degree of merit. Moreover, the period of merit is limited by the decree of God to this life, because it is fitting that the creature should increase and progress, during his probation, toward the full measure of his perfection, and should afterward remain in that perfection when he has arrived at his term. We think, therefore, that we have made it plain enough that good works have a merit of condignity in relation to eternal life, and nevertheless derive this merit from the promise and appointment of God, subject to such conditions as he has seen fit, in his sovereign wisdom and liberality, to establish.
