V.22-26 Possibly the blind man’s experience was like the disciples — they saw only partially. The Lord keeps on, until the blind man saw clearly. When the Holy Spirit came down, then the disciples saw plainly.
V.27-33 The Lord asks a vital question. Upon Peter’s reply, He tells them not to tell any about Him. Why? Because He had been completely rejected. So He turns their thoughts to the cross. But notice He does not say that Christ must suffer, but the “Son of Man.” This is His rejection title, and also that by which He shall be known when He comes in glory and power (Matt. 26:4646Rise, let us be going: behold, he is at hand that doth betray me. (Matthew 26:46)). Peter did not understand that the cross was the road to glory.
V.33 The Lord knew that what Peter had just said was not understood by the other disciples, so He speaks very strongly to Peter.
V.34-38 To follow the Lord down here is not an easy road. It will mean taking a low place, enduring sorrow and loneliness. But the end of that road is glory.
