For those who have asked, here are some of the main themes inspiring each song:
Saints and Sinners - Justification (Ephesians 2:8–9)
My Lord, My Lord - The knowledge of God (Matthew 7:21–23; Matthew 25:31–46)
Mrs. Jellyby - Missions/family (Bleak House, Dickens)
Shrinking - Ecclesiology/prosperity gospel
Teach Me How to Pray - Prayer/Moses/Garden of Gethsemane
Son of Promise - Abraham & Isaac (Genesis 22)
To Be Human - The Incarnation
With a Kiss - Repentance/Judas
To See You Alone - The Transfiguration (Matthew 17:1–8)
You Won't Stop Loving Me - Grace/Love (Psalm 139:8; Ephesians 3:18)
I hope to write/record some video explanations for each one soon!
