Stephen saw Jesus STANDING at the right hand of God

They arrested Jesus and took him to face the Sanhedrin, NIV Matthew 26:

63b The high priest said to him, “I charge you under oath by the living God: Tell us if you are the Messiah, the Son of God.”
64 “You have said so,” Jesus replied. “But I say to all of you: From now on you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven.”

These evil people will see Jesus sitting at the right hand of God.

Later, they stoned Stephen in Acts 7:

55 he, full of the Holy Spirit, gazed into heaven and saw the glory of God, and Jesus standing at the right hand of God.

Now, Stephen saw Jesus standing.

Jamieson-Fausset-Brown explained:

Why "standing," and not sitting, the posture in which the glorified Saviour is elsewhere represented? Clearly, to express the eager interest with which He watched from the skies the scene in that council chamber, and the full tide of His Spirit which He was at that moment engaged in pouring into the heart of His heroical witness, till it beamed in radiance from his very countenance.
