The title is the question the high priest asked of Jesus as He was being tried for His “crimes” (Matthew 26:63).
When Jesus opened His mouth it was acknowledging the words of the high priest with a loud “Yes!”…
“Jesus saith unto him, ‘Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of Man sitting on the right hand of power, and coming in the clouds of heaven.’” Matthew 26:64 (KJB)
From F. B. Meyer on verses 57-66 of Matthew 26:
“This meeting of the Jewish leaders had been hastily summoned; but their difficulty was to substantiate a charge that would warrant the death sentence. They had to go back to the beginning of Christ’s ministry for the one charge that seemed sufficient for their purpose. But see Joh_2:19; Mar_14:58. In the meanwhile our Lord opened not His mouth. He left His reputation in the care of the Father, to whom He also committed His soul. It is a good example to follow. Do what is right and let God vindicate you!
It was only when Jesus was directly challenged as to His unique relationship to God, that He opened His lips. There is an evident reference in His words to Dan_7:13-14. The court instantly recognized that in His reply He claimed to be equal with God. To be the Son of God was to be God. See also Joh_5:18. Note that word henceforth, which suggests that though it is hidden from us, the Kingdom is already set up, as was David’s even when Saul was still on the throne.” Through the Bible Day by Day by F. B. Meyer
For those of you who say that Jesus never said He was and is the Son of God or God the Son; that is exactly what He is admitting to in the words above. That is why He is charged with blasphemy by the court of human religion.
O turn to Jesus Christ today, believe Him, believe His word, trust the work of the cross of redemption to bring to God, faith, and salvation.
