17 But Jesus, being aware of it, said to them, “Why do you reason because you have no bread? Do you not yet perceive nor understand? Is your heart still hardened? 18 Having eyes, do you not see? And having ears, do you not hear? And do you not remember?” (Mark 8:17–18, NKJV)
Jesus expected His apostles to understand His warning against the leaven of the Pharisees and Herod, but they were only thinking about physical bread (Mark 8:14-16). He said their hearts were “still hardened” because they could not perceive (understand) the meaning of His warning. They needed to comprehend the corrupting influence of their error, immorality, and hypocrisy (Matt. 16:11-12; Luke 12:1). Here is a lesson on being distinctive hearers. It matters how we hear Christ’s word. Jesus said, “Therefore take heed how you hear” (Luke 8:18). The Pharisees disputed with Jesus and rejected His signs (Mark 8:11-12). Like their forefathers, they were “stiff-necked and uncircumcised in heart and ears” (Acts 7:51-52). We must have open hearts to receive the gospel of Christ, lest the leaven of the Pharisees, the Sadducees, and the Herodians corrupt us. (Demanding preaching that scratches itching ears still happens, 2 Tim. 4:3-4.) When we resist the word of Christ, we are disputing with and testing Jesus just like the unbelieving Pharisees (Mark 8:11). May we humbly, reverently, and obediently accept the word of Christ. We understand Christ’s teachings when our will is to do the will of God (John 7:16-17; Eph. 3:3-4; Heb. 5:12-14). Open your heart to the gospel of Christ, and you will be blessed (Acts 17:11-12).
