The Bible records that Jesus was amazed 2 times. One is recorded in Matthew 8 where Jesus is amazed at the faith of the Centurion. The other is here in Mark 6 where Jesus is amazed at the unbelief in His own hometown. Luke 4 records His first visit to Nazareth and they wanted to kill Him. Now during His second and last visit their belief amazes Him. The Disciples have seen people plead with Jesus to leave their town (5:17). They have seen people laugh at Jesus (5:40). Now they get a firsthand glimpse of what amazing unbelief looks like.
