In general, birth order in the Bible reflects the progression of spiritual states, but the specifics of those states depends greatly on context: who the people in question are, and whether we’re talking about spiritual states as they flow to us from the Lord, or spiritual states as we advance through them to approach the Lord. For example, Esau was older than Jacob (by minutes, but it mattered), and as the elder represents a more internal spiritual state: the desire for good, and the ideas that flow from that desire. Jacob represents a more external state: the understanding of ideas that lead to good. The switched blessing, with Jacob getting the blessing Isaac meant for Esau, shows that to progress in life we need to put our understanding first for a while, though ultimately our loves will catch up and ultimately determine our true character. A similar thing happens when Jacob crosses his hands to give Ephraim, the younger of Joseph’s sons, the primary blessing over his older brother Manasseh. Both those cases describe blessings coming from the Lord, with the highest states coming from Him and extending down through lower states to get to us. There is a sort of opposite dynamic in the story of Leah and Rachel. There Jacob (representing the Lord himself, as a human, in His childhood) is advancing from more external states to more internal ones. In this case, then, the older daughter, Leah, represents a more external state which He had to work through to reach the more internal state represented by Rachael.

Consider the beautiful but cryptic statements of John 1:1:

"In the beginning was the Word, and the Word was with God, and the Word was God."

God's love has always been and will always be infinite and perfect. That means the expression of God's love -- His truth -- has also always been and will always be infinite and perfect.

The Lord has shared this truth with us in various ways since the beginning of humanity. The earliest people received truth directly, flowing into the inner parts of their minds from heaven. Later, people understood it through nature seeing the Lord's love expressed in mountains, trees, rivers, and the sun, moon and stars. By using natural language as a container for spiritual language, the Lord expressed truth within the Bible inside its stories, laws and prophecies. When humanity reached its lowest point, God took on a human form and walked among us as Jesus. In this way, the Lord brought us Divine truths in an accessible and tangible way. By accepting and loving the Lord as Jesus we can open ourselves to His love.

Finally, the Heavenly Doctrine received through the pen of Emanuel Swedenborg are themselves a container for Divine Truth, both in speaking plainly about heaven and by unlocking the truth as it is contained in the Bible.

The Word itself is Divine Truth; the Lord's expression of love has and never will change.
