How does Jesus’ teaching challenge human understanding?

In John 6:60, many of Jesus’ disciples found His teachings to be 'hard' and difficult to accept. This reaction emphasizes how the gospel challenges human understanding and preconceived notions about salvation. Jesus’ assertion that no one can come to Him without the Father’s drawing confronts the common belief in human autonomy in spiritual matters. This offense is a hallmark of gospel truth, revealing the stark reality that the natural man resists the grace of God. Therefore, understanding this dynamic is essential for grasping the sovereign nature of God's work in salvation.
