The germ of faculties

This is interesting. Here is Archibald Alexander from his Brief Compend of Bible Truth:

For context, he is describing the life of heaven.

"Their minds will, no doubt, be wonderfully enlarged; and it is no extravagant idea, and is altogether consistent with analogy, to suppose, that we have now in our mental constitution, the germ of faculties which have never been developed in this world, because here their exercise was not needed; but which, upon our transition into the celestial world, will be brought into full activity..."

This is useful. When we make efforts to develop and use higher centers, for instance, we can see it as not just for the here and now, but it may just be something that will manifest when we are in the spirit and in glorified bodies. I.e. the effort might seem like chasing unicorns here while in the flesh, but what we attain will be fully useful when in the spirit and in the new heavens and earth.
