God has called certain faithful followers to receive his gospel first and to carry it unto all the world. The fact that his gospel was to go unto all the world is evidence of his love for all mankind. Jesus, who was made part of the godhead before the world was (John 1:1-3, 14) , volunteered to be the Savior of all mankind before the world was (1 Peter 1:19-21). Jesus wanted us all to have the opportunity to repent and be forgiven of our sins if we would only repent and seek that forgiveness from him. Jesus was a lamb without blemish or spot. In other words, Jesus was the only one born in this world to have never sinned. Yet he suffered for the sins all mankind. So great was his suffering that it caused himself to bleed great drops of blood from every pore of his body. Yet Jesus did not sin even once in this life. All his sufferings were unjust and he deserved a recompense for his unjust sufferings. As a recompense, he was given the right to forgive the repentant sinner. This extended to all mankind since he suffered for all mankind's sins. His sufferings were so great that he gained the recompense that would be the key to all our salvation. Can you imagine the love one must have to sacrifice ones self for the billions or possibly trillions who have ever lived on this earth and ever will live on this earth, and possibly for others on other earths. I don't think the average person could have suffered as he did without dying. As the Son of God he was the offspring in this life of God the Father as well as Mary. Maybe this gave him the capacity to suffer much more than the average mortal being without dying. But why would he put himself through all the suffering and pain and then be whipped and beaten and finally have spikes driven through his body to hang him on a cross to die? The answer is that he did it all because he loved us so dearly that he was willing to go through all that for each and everyone of us. His atonement is for each and everyone of us and his gospel is to go unto all that are in the world.
John 3:16
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
