Arcana Coelestia # 43
43. Verse 22 And God blessed them, saying, Be fruitful and multiply, and fill the waters in the seas; and let birds be multiplied upon the earth.
Everything that has life in it from the Lord is fruitful and multiplies without limit. This does not happen during a person's lifetime, but in the next life it does so to an astonishing extent. In the Word 'to be fruitful' has reference to matters of love, while 'to multiply' has reference to matters of faith. The fruit of love contains the seed by which it multiplies itself to so great an extent. The Lord' s blessing also means, in the Word, fruitfulness and multiplication, for they are the outcome of that blessing.
Verse 23 And there was evening, and there was morning, a fifth day.
Bless
The Lord in essence is perfect love expressed as perfect wisdom. He created us so that He could love us, give us love and wisdom of our own, and thus be united with us. This is the ultimate blessing, for us to receive His love and wisdom and to be together with Him, and all other forms and meanings of "blessing" flow from it. This flow, however, takes many different forms in the Bible. When people receive the Lord's blessing, it illustrates how His love and wisdom flow into us in forms that fit the spiritual state people represent in the Word. When people bless the Lord, it indicates an acknowledgment that life and all its gifts come from Him and shows a desire to accept them and be conjoined. When people bless each other, it represents the desire to share good desires and true ideas as much as possible.
