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.

10154. 'And I will be their God' means the Lord's presence and His influx into truth in the Church. This is clear from the meaning of 'being their God' as the Lord's presence and His influx into truth - into truth because in the Old Testament Word the Lord is called God where truth is the subject, but Jehovah where good is the subject. This also goes to explain why angels are called gods, because they are recipients of Divine Truth from the Lord, and in addition why in the original language the plural word Elohim is used to denote God; for truths are many but good is one, Matthew 19:16-17.

The Lord is called God where truth is the subject but Jehovah where good is the subject, see 2586, 2769, 2807, 2822, 3921, 4287, 4402, 7010, 9167.

Angels are called gods, because they are recipients of Divine Truth from the Lord, 4295, 4402, 7268, 7873, 8192, 8302, 8867, 8941.

In the Word Jehovah means the Lord, see the places referred to in 9373; and in Isaiah He is called explicitly 'Father from eternity' and also 'God',

To us a Boy is born, to us a Son is given, and the government will be upon His shoulder; His name is called, God, Hero, Father of Eternity, Prince of peace. Isaiah 9:6.

And in the same prophet,

A virgin will conceive and bear [a son], and His name will be called Immanuel, that is, God with us. Isaiah 7:14; Matthew 1:23.

The meaning of the words here 'I will be their God' as the Lord's presence and His influx into truth is also evident from the fact that 'I will dwell in the midst of the children of Israel' means the Lord's presence and His influx through good. For wherever good is the subject in the Word, so too is truth, on account of the heavenly marriage, which is that of goodness and truth, in every single part of the Word, see the places referred to in 9263, 9314.
