No one has greater love [no one has shown stronger affection] than to lay down (give up) his own life for his friends. (Joh 15:13, Amplified Bible).
Many Christians all over the world recognize the last week before Easter, as the Hoy Week. It symbolizes the week when Jesus faced the sentence of death, not for what He did wrong but as a sacrifice for the whole world.
Was it easy for Him? Definitely not! Imagine Him in the garden, knowing the task which lay before Him. Imagine the description of His sweat falling from His body as great drops of blood. I believe Jesus went through any trauma you can speak of; psychological, physical and mental.
