Isaiah and Mark Twain

I'm reading Isaiah as a way to keep the Bible in mind while I write about HF. I'm not sure why. Partly because Isaiah is quoted so often by Jesus, and others.
What I am finding in early reading is that the oracle nature of I is also what I imagine Twain is at with HF- that is the admonition of repentance, not for Israel, but for the US in 1885. Isaiah just comes out and says it. Twain tells a story, and uses Socratic irony to nudge the reader toward repulsion at racism and supremacy of power and greed, not to mention white power.

I've not yet begun reading HF; I'm struggling with whether to read up on other material that I need to keep in mind before I begin looking for clues about spiritual awakening.

Yesterday I was thinking about Fowler's stages of faith, and that early stage of blind acceptance of the anthropromorphic nature of God, as the puppeteer. I recall that in early HF his aunt is explaining the value of prayer as a way to ask for what you want, so I hope to write about that connection.

That reminds me, that I think my approach is going to be to look for parts of the story to pull out to illustrate a particular 'growth spurt'. Those, I hope, will be the basis for the retreats that I hope to develop.

In Isaiah 6 is the famous dialog 'Here am I, send me' after God touches, through a seraph, his lips with a burning coal. And then comes the dialog that Jesus repeats occasionally in his own ministry: keep listening but do not comprehend, keep looking but do not understand.
Of course the first inclination is to think " why would God do that? Doesn't God want us to listen and understand? Isn't that God's job?"
But before redemption, God needs hearts to be hardened a little further before redemption is possible.

So let's look for the people surrounding Huck to be on the cusp of redemption, but then get delayed a little longer.

Also in I 7, Therefore the Lord himself will give you a sign. Look, the young woman is with child and shall bear a son, and shall name him Immanuel (God is with us).
