S – He was not able to do a miracle there, except that he laid his hands on a few sick people and healed them. ⁶ And he was amazed at their unbelief. He was going around the villages teaching. 

Mark 6:5–6 CSB

O – Commentary:  There was no limitation on His power, but His purpose was to perform miracles in the presence of faith. Only a few here had faith to come to Him for healing.

Even Jesus was amazed (ethaumasen, “astonished”; cf. 5:20; 12:17; 15:5, 44) at their unbelief, their unwillingness to believe that His wisdom and power were from God. So far as is known, He never returned to Nazareth

 “Mark,” in The Bible Knowledge Commentary: An Exposition of the Scriptures,

A – Where God had no limitations, the faith lacked.  While the healing displayed God’s power and compassion, relationship and faith were Jesus’ goals.  When you are familiar with someone, it is hard to believe they can be more than you know.  “Astonished” is a strong word.  It tells me it was beyond Jesus’ comprehension that they could not get there.  Yet, the struggle of faith is real.

R – Lord, help my faith to grow.  Where I have become familiar or stubborn, make my heart soft to see you without limitation.  Help me to invite you into situations that stretch my faith and belief in you.  You can do it and I know that.  Help my unbelief.
