Listened to your essay, and at first, I was a bit worried but now not so much. Loved your house parable! (My "5 minutes ago" response is below,)

In this response I'd like to add Matthew 24:13 - "but the one who stands firm to the end will be saved." So, I really like your ending paragraph's "This gospel is the power of God to save us, and it is the main thing. It will always be my central belief."
