984. 'Filling the earth' means residing with the external man. This is clear from the meaning of 'the earth' as the external man, dealt with several times already. In the case of someone who is regenerate the goods of charity and the truths of faith have been implanted in his conscience. And because they have been implanted by means of faith - that is, through hearing the Word - they lodge first of all in his memory, which belongs to the external man. Once he has been regenerated and the internal man is active, fruitfulness and multiplication follow too; goods that stem from charity reveal themselves in affections that belong to the external man, while truths of faith do so in his memory, where they grow and multiply in both places. Any regenerate person may know the character of this multiplying, for things of a confirmatory nature are coming in all the time, both from the Word and from the rational man, as well as from known facts, to confirm him more and more. It is the outcome of charity, with the Lord alone working by means of that charity.
