Romans 11:6-8

11:6 And if it is by grace, it is no longer by works, otherwise grace would no longer be grace. 11:7 What then? Israel failed to obtain what it was diligently seeking, but the elect obtained it. The rest were hardened, 11:8 as it is written,

“God gave them a spirit of stupor,

eyes that would not see and ears that would not hear,

to this very day.”
