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?”
When Jesus spoke of “hardened” hearts in this passage, He wasn’t referring to scribes, Pharisees, or Roman officials who bitterly opposed Him. Oh, their hearts were hardened too; but in Mark 8, He was speaking to His closest followers—the Twelve. Despite the miracles He performed and the instructions He gave, the truth about His power hadn’t sunk into their minds. Their hearts were like fields so dry and hard that the needed rain simply ran off without soaking into the soil. They had seen Jesus feed 5,000 in Mark 6, yet they didn’t know how He could feed 4,000 in Mark 8.
Healthy hearts soak up the water of the Word. They are furrowed by faith and tilled by trust. That’s the kind of heart the Lord desires. Don’t rebel or distrust Him. Hebrews 6:7 says, “When the ground soaks up the falling rain and bears a good crop for the farmer, it has God’s blessing” (NLT).
When we thus forget the works of God, and distrust him, we should chide ourselves severely for it, as Christ doth his disciples here: “Am I thus without understanding! How is it that my heart is thus hardened?”
