R. V. G. Tasker, writing in the Tyndale New Testament Commentary on The Gospel According to St. John, gives an electrifying look at Christ’s arrest in Gethsemane in John 18:1-8:
Jesus had left the upper room with the express intention of going forth to meet the prince of evil and his human satellites…for He had already resisted the temptation to pray ‘Father, save me from this hour’, knowing that if that prayer had been granted, there would have been no glorification of His Father, and mankind would never have known the wonder of His redeeming love…
So when He crosses the brook Cedron to a garden (I), which had been a favourite resort for Himself and His disciples, what is happening is that the second Adam is deliberately entering upon the final conflict with the prince of evil, reversing the situation in the garden of Eden where the serpent took the initiative in the assault upon the first Adam.
When Judas, now completely in the grip of Satan (see xiii.2), crosses the garden, leading a fully-armed band of assailants consisting of temple police and Roman soldiers (3), Jesus knowing all that is going to happen to Him and knowing that it is in accord with His Father’s will, goes out to meet them and twice calls upon them to name the person they are looking for (4, 7). And when they twice reply Jesus of Nazareth, He says in words of majesty and divinity, I am he. [Tasker, 124]
