Arcana Coelestia #12

And because at this point he starts to act from faith and also simultaneously from love, he becomes a spiritual man, who is called an image. The spiritual life of that man finds its delight in, and is sustained by, the things which are associated with cognitions of faith and with charitable acts, which are called his food; and his natural life finds its delight in, and is sustained by, those which belong to the body and the senses. The latter give rise to conflict until love rules and he becomes a celestial man.

The number three in the Bible represents completeness. That's why Jesus rose on the third day after the Crucifixion -- his transformation was complete. It's why Elijah stretched himself on the dead child three times, why Jonah was in the belly of the fish for three days, why the Lord called Samuel three times, and many more. It's also reflected in the fact that there are three levels of heaven, three levels of hell, three levels to human life and, ultimately, three aspects of the Lord Himself: Father, Son and Holy Spirit.
