Heavenly Life to be Conferred on Adam
Although the Scripture does not make express mention of a heavenly life to be conferred on Adam, it is with sufficient clearness gathered by legitimate consequence from the opposed threatening of eternal death and from the sacramental seal of this promise by the tree of life (the signification of which was surely known to man). For although Moses describes it obscurely (as most of the things pertaining to that covenant, upon which, as the shadow of a fleeing image, he throws only scattered rays of light to represent its evanescence [ἀφανισμὸν]), yet there can be no doubt that these things were more distinctly revealed to the first man.
