According to the Writings, the Lord has been expressing his love for us for as long as we have existed, varying its form to fit our ability to receive it. Among the earliest people – in what the Writings call the Most Ancient Church – this was relatively direct, with divine truth flowing through heaven into people’s internal minds. People then thought of the Lord as a spiritual human, not a natural one, but the spiritual world was as real to them as the natural world was.

But people eventually turned away, wanting to use their own intelligence to explore what is true. So the Lord adjusted, leading people to know Him through his imprint on the natural world, seeing the truth of His love in everything from the alignment of the stars to the most common plants and animals. But again people turned away, using that knowledge to think for themselves and serve themselves.

So the Lord adjusted again, imprinting His love on the stories and laws of the Old Testament, on the songs of the Psalmist and the visions of the prophets. People were largely turned away, but if they would read these words and follow these rules in their external lives, He could still flow into their internals. But again people people rejected Him, making the laws into utterly external things and twisting the prophecies to suit their own desires. At that point the darkness was nearly complete, with barely a glimmer of knowing the Lord to be found anywhere.

So the Lord adjusted again, imprinting His love – the divine truth – into natural human flesh with the birth of Jesus. Jesus would preach the love and caring that were hidden within the Old Testament, and would put ideas in new forms, that made love of the Lord and love of the neighbor paramount – once more a pure expression of the Lord’s love.

The Writings also say that Christians ultimately turned away from Jesus’s true message, first by dividing the idea of God into three people and later by making salvation simply a matter of belief – of faith alone – rather than a matter of belief that flows into life. And they say that they themselves are a new expression of divine truth, re-establishing the meaning of the Bible and the true messages delivered by the Lord during His life in the natural world.

Clearly, then, the "light" of divine truth has repeatedly "shone in the darkness" of the human mind. And repeatedly people have not comprehended it.

3134. 'Who said, Thus the man spoke to me' means the leanings of truth in the natural man. This likewise is clear from the affection that occurs here, and also from what the man, or Abraham's servant, said to Rebekah, from which it is evident that the leanings of truth are meant; and from the meaning of 'the man' as truth, dealt with in 265, 749, 1007, here truth within the natural man and coming from the Divine, as he is Abraham's oldest servant, who means the natural man, see 3019. In the prophetical part of the Word especially 'man' (vir) is a word that occurs often - in the expressions 'man and wife', 'man and woman', 'man and inhabitant', and also 'man and human being' (vir et homo). In those expressions 'man' in the internal sense means that which belongs to the understanding, which is truth, while 'wife', 'woman', 'inhabitant', and 'human being' mean that which belongs to the will, which is good. As in Isaiah,

I look, and there is no man, and from these there is no counsellor. Isaiah 41:28.

'No man' stands for no one having intelligence, and so for no truth.

[2] In the same prophet,

I came, and there was no man; I called and no one answered. Isaiah 50:2.

Here the meaning is the same. In the same prophet,

Truth has stumbled in the street, and uprightness has been unable to come in, and truth has been removed, and he who retreats from evil is insane. Jehovah saw, and it was evil in His eyes that there was no judgement. And He saw, and there was no man, and wondered. Isaiah 59:14-16.

'No man' clearly stands for no one having intelligence, and so in the universal sense for no truth. These verses in Isaiah refer to the final period of the Church when no truth at all exists any longer. Hence the statement 'truth has stumbled in the street, uprightness cannot come in, and truth has been removed'. 'The street' too has reference to truth, see 2336, as does 'judgement', 2235. In Jeremiah,

Run to and fro through the streets of Jerusalem and see now, and take note, and search in its broad places, if you find a man, if anyone is executing judgement and seeking truth. Jeremiah 5:1.

Here also 'a man' clearly stands for one having intelligence, and for truth. In Zephaniah,

I will make their streets desolate with none passing through; their cities will be devastated, with not a man and not an inhabitant there. Zephaniah 3:6.

'Not a man' stands for no truth, 'not an inhabitant' for no good, 2268, 2451, 2712. The same occurs in many other places besides these.
