Let us hear from our Lord, who proclaimed, "False witnesses have risen up, accusing Me of things which I did not know." (Psalm 34:11). Yet we may ask our Lord: What was it that You were unaware of? Did You truly know nothing? Were You not aware of the intentions of those who brought false accusations against You? Did You not anticipate their deceit? Did You not willingly place Yourself in their grasp? Did You not come to endure their suffering? What is it that You did not know? He was without sin, which is why He was untouched by sin—not because He lacked the ability to discern but because He never committed it. Such expressions are common in daily conversations; you might say of someone, "He knows he cannot stand," meaning he indeed cannot stand.

He lacks the knowledge of doing good because he does not perform good deeds; he is unaware of evil because he does not engage in wickedness. What was it that Christ was unaware of, to the point of not committing blasphemy? For this very reason, He was interrogated by His accusers, and because He uttered the truth, they deemed it blasphemy. (Matt. 26:65) And by whom was this claim made? By those who, as it is written, repaid Me evil for good, rendering My soul desolate.
