The Holy Spirit is the only source there is.
The written word holds
no particular value.
....according to the written word anyway.
Genesis 1:1
In the beginning, God created the heavens and the earth.
Psalm 19:1-14
The heavens declare the glory of God, and the sky above proclaims his handiwork. Day to day pours out speech, and night to night reveals knowledge. There is no speech, nor are there words, whose voice is not heard. Their voice goes out through all the earth, and their words to the end of the world. In them he has set a tent for the sun, which comes out like a bridegroom leaving his chamber, and, like a strong man, runs its course with joy.

For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.

Lift up your eyes on high and see: who created these? He who brings out their host by number, calling them all by name, by the greatness of his might, and because he is strong in power not one is missing.

When I look at your heavens, the work of your fingers, the moon and the stars, which you have set in place,

“Can you bind the chains of the Pleiades or loose the cords of Orion? Can you lead forth the Mazzaroth in their season, or can you guide the Bear with its children?

So God created man in his own image, in the image of God he created him; male and female he created them.

But I ask, have they not heard? Indeed they have, for “Their voice has gone out to all the earth, and their words to the ends of the world.”

Thus says the Lord, who gives the sun for light by day and the fixed order of the moon and the stars for light by night, who stirs up the sea so that its waves roar— the Lord of hosts is his name:

And the glory of the Lord shall be revealed, and all flesh shall see it together, for the mouth of the Lord has spoken.”
Jeremiah 31:31-34
“Behold, the days are coming, declares the Lord, when I will make a new covenant with the house of Israel and the house of Judah, not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the Lord. But this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. And no longer shall each one teach his neighbor and each his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more.”

“This is the covenant that I will make with them after those days, declares the Lord: I will put my laws on their hearts, and write them on their minds,”

And you show that you are a letter from Christ delivered by us,
written not with ink
but with the Spirit of the living God,
not on tablets of stone
but on tablets of human hearts.

I delight to do your will, O my God; your law is within my heart.”
