John 3:16
New American Standard Bible (NASB)
16 “For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.

Explanation: God loved us sooo much that he gave His ONLY BEGOTTEN SON to Die for US!! He gave Himself up to die for us!
God is not like the other, made up gods. He didn’t have many sons/daughters with innocent unsuspecting girls like Zeus did; no He had one son, conceived by the Holy Spirit. And God’s son isn’t half god half human, no, Jesus was fully God and fully man. God only had one son, and He gave Jesus up to die the worst death possible to save us, the sinners, murderers, adulterers, tax collectors, politicians, drug abusers, alcoholics, and criminals. How many of us, parents or not, would even think of giving up our (future or present) sons or daughters, or ourselves, to die for a bunch of people like that? God did because He loves us so much! He wanted to see us live with Him, not in hell for all eternity. He loves us so much that He gave His only son to take on our sins and transgressions and take the ultimate punishment for them! Ever wonder why Jesus fell? I believe that it was not only because was He weak but because every fiber that made up that cross was 1000s of our sins; can you imagine having literally the weight of the entire world, past, present, and future on your shoulders? Well, that’s what Jesus had on His. That type of indescribable love is exactly what God feels for us. Every second that passes God is thinking about YOU. At the moment you are present in the womb He assigns an angel to protect you! An angel that could be praising God in heaven is, instead, by your side through everything! God has assigned you a heavenly body guard because he cares so deeply for you. He cares so much that He wants to be with you. He wants to have a relationship with you so badly that He died for you!! So whenever you need guidance or reassurance that God is there, look up John 3:16 and think of this.
Description of the Crucifixion:
Medical experts, historians and archaeologists have examined in detail the execution that Jesus Christ voluntarily endured. All agree that he suffered one of the most grueling and painful forms of capital punishment ever devised by man. Here is a brief summary of some of the things we know about his last hours from history, archaeology and medicine…
Jesus had the weight of the world on his shoulders. Even before the crucifixion began, he clearly had physical symptoms associated with severe stress. The night before the execution, his disciples reported seeing Jesus in “agony” on the Mount of Olives. Not only did he not sleep all night, but he seems to have been sweating profusely. So great was the stress that tiny blood vessels were rupturing in his sweat glands and emitting as great red drops that fell to the ground (see Luke 22:44). This symptom of severe stress is called hematohidrosis.
Jesus was physically exhausted and in danger of going into shock unless he received fluids (which he apparently did not).
Having previously been beaten by the Jews, it was now the Romans' turn. The beatings administered by Roman soldiers are well known to be very bloody, leaving lacerations all over the body. Romans designed their whips to cut the flesh from their victim's bodies. These beatings were designed to be painful to the extreme. It would also cause a fluid build-up around his lungs. In addition, a crown of thorns was forced into his scalp which was capable of severely irritating major nerves in his head, causing increasing and excruciating pain, as the hours wore on.
In Christ's severely stressed condition, these beatings were easily enough to kill him. His body was horribly bruised, cut and bleeding. Having had no nourishment for many hours, and having lost fluids through profuse sweating and much bleeding, Jesus would have been severely dehydrated. This brutal torture would certainly be sending him into what doctors call “shock,” and shock kills.
In addition, Jesus was forced to carry the wooden beam on which he would die. Imagine the effect of carrying a heavy weight if you were in that condition.
Hung completely naked before the crowd, the pain and damage caused by crucifixion were designed to be so devilishly intense that one would continually long for death, but could linger for days with no relief.
According to Dr. Frederick Zugibe, piercing of the median nerve of the hands with a nail can cause pain so incredible that even morphine won't help, “severe, excruciating, burning pain, like lightning bolts traversing the arm into the spinal cord.” It’s like hitting your funny bone times a thousand. Rupturing the foot's plantar nerve with a nail would have a similarly horrible effect.
Furthermore, the position of the body on a cross is designed to make it extremely difficult to breathe.
Frederick Farrar described the intended, torturous effect: “For indeed a death by crucifixion seems to include all that pain and death can have of horrible and ghastly—dizziness, cramp, thirst, starvation, sleeplessness, traumatic fever, tetanus, shame, publicity of shame, long continuance of torment, horror of anticipation, mortification of untended wounds—all intensified just up to the point at which they can be endured at all, but all stopping just short of the point which would give to the suffer the relief of unconsciousness.”
One doctor has called it “a symphony of pain” produced by every movement, with every breath; even a slight breeze on his skin could bring screaming pain at this point.
Medical examiner, Dr. Frederick Zugibe, believes Christ died from shock due to loss of blood and fluid, plus traumatic shock from his injuries, plus cardiogenic shock causing Christ's heart to fail.

James Thompson believed that Jesus did not die from exhaustion, the beatings or the 3 hours of crucifixion, but that he died from agony of mind producing rupture of the heart.
His evidence comes from what happened when the Roman soldier pierced Christ's left side. The spear released a sudden flow of blood and water (John 19:34). Not only does this prove that Jesus was already dead when pierced, but Thompson believes it is also evidence of cardiac rupture. Respected physiologist Samuel Houghton believed that only the combination of crucifixion and rupture of the heart could produce this result. There is no question that it was painful beyond words.
