We do not know, we cannot tell, no mortal mind can conceive the full import of what Christ did in Gethsemane.
We know He sweat great gouts of blood from every pore as He drained the dregs of that bitter cup His Father had given Him.
We know He suffered, both body and spirit, more than it is possible for man to suffer, except it be unto death.
We know that in some way, incomprehensible to us, His suffering satisfied the demands of justice, ransomed penitent souls from the pains and penalties of sin, and made mercy available to those who believe in His holy name.
We know that He lay prostrate upon the ground as the pains and agonies of an infinite burden caused Him to tremble and would that He might not drink the bitter cup.
He suffered for each of us individually in the Garden of Gethsemane. He knows each of us personally and knows what we need and how we can be led through trials and repentance. As Elder McConkie said, "in some way, incomprensible to us, his suffering satisfied the demands of justice." I know I will never completely comprehend what suffering he experienced, but I look at the strength that he had and who he was as a man and the life he lived. I see that even Christ, the son of God felt this was more than he could endure. He knew it must be done and I am sure He had spent much of his life preparing for this moment, yet when it came it felt like it was too much, even for Him. Henry B. Eyring said this:
The Savior showed us that humility. you have read of how He prayed in the garden while He was suffering a trial on our behalf beyond our ability to comprehend or to endure, or even for me to describe. you remember His prayer: “Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done.”
He knew and trusted His Heavenly Father, the great elohim. He knew that His Father was all-powerful and infinitely kind. The Beloved Son asked for the power of deliverance to help Him in humble words like those of a little child.
The Father did not deliver the Son by removing the trial. For our sakes He did not do that, and He allowed the Savior to finish the mission He came to perform.
Then He was taken to be persecuted, whipped and hung on the cross for our sins, sadness, shame and sickness. He continued to suffer for each of us individually so that he could truly have empathy for us and understand and help each of us in the way we individually needed it. Today I thought about how he hung for all to see as a common criminal. I thought about how humiliating it must have been. His clothes were taken, he was mockingly adorned with a crown of thorns and hung as criminal. While he suffered many pains for each of us, he even suffered and knows the feeling of embarrassment and public humiliation. Then as he came to the end of his suffering in John 19:30 it says:
