Jesus said to them, “Is this not the reason you are wrong, because you know neither the Scriptures nor the power of God?
Mark 12
This is a circular proof text for sola scriptura, maybe?
Here’s additional insight to the above text:
The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. The spiritual person judges all things, but is himself to be judged by no one. “For who has understood the mind of the Lord so as to instruct him?” But we have the mind of Christ. 1 Cor 2
John 3:3
Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.”
