In his book on language, British diplomat Lancelot Oliphant (1881–1965) observed that many students give correct answers on tests but fail to put those lessons into practice. “Such undigested knowledge is of little use,” declared Oliphant.

Author Barnabas Piper noticed a parallel in his own life: “I thought I was close to God because I knew all the answers,” he said, “but I had fooled myself into thinking that was the same as relationship with Jesus.”

At the temple one day, Jesus encountered people who thought they had all the right answers. They were proudly proclaiming their status as Abraham’s descendants yet refused to believe in God’s Son.
