Are you saying you lack the spiritual ability to address scripture?
Why are you not able to address these scriptures?
Luke 8:13 (LEB) — 13 And those on the rock are those who receive the word with joy when they hear it, and these do not have enough root, who believe for a time and in a time of testing fall away.
and why it was necessary to harden these so they do not believe
John 12:40 (LEB) — 40 “He has blinded their eyes and hardened their hearts, lest they see with their eyes and understand with their hearts and turn, and I heal them.”
