Many times Jesus said to His followers, “You have heard it said… but I say to you...” He was intent on correcting their misunderstanding of the heart of the Law, and thus, the Father's heart. As a teacher, I know people “hear” things differently, sometimes hearing things I didn't even say! No doubt Jesus was aware of this “I-thought-I-heard-you-say” phenomenon, because He often said, “Let him who has ears to hear, hear...”
Allen Greenspan eloquently captured the essence of this hearing problem: “I know you think you understand what you thought I said, but I'm not sure you realize that what you heard is not what I meant.” So, Paul says, “For this reason, we must pay much closer attention to what we have heard” (Heb. 2:3). Even as Jesus warned against those who have ears but fail to hear, and worse, cannot remember what they heard (Mark 8:18).
There is a spiritual principle that asserts ‘you cannot live beyond your vision’—we are limited by what we see. The same goes for hearing. Jesus said, “Be careful what you hear. The closer you listen, the more understanding you will be given—and you will receive even more” (Mark 4:24, NIV, NLT). Did you know that Charles Stanley always draws emphasis to his important points by saying, "Now listen up."
