He said, “I am the voice of one shouting in the wilderness, ‘Make straight the way of the Lord,’ as the prophet Isaiah said.”

This was to fulfill what Isaiah the prophet said: “Lord, who has believed our message? And to whom has the arm (the power) of the Lord been shown (unveiled, revealed)?”

Therefore they could not believe, for Isaiah said again,

Isaiah said these things because he saw His glory and spoke about Him.
