God the Father, God the Son and God the Holy Spirit created a Perfect
Plan:  One of Them must go down to Earth and take the punishment for
mankind's rebellion.  God the Son, Jesus Christ, volunteered to be the One.

God's Plan:  1) Prepare a Perfect Sacrifice;  2) Require Him to live a perfect
life;  3) Have Him make Disciples of ordinary men;  4) Have Him teach those
men to teach others;  5) Have Him stand silent when accused;  6) Have Him
endure the punishment of God for all mankind for all of human history; past,
present and future;  7) Execute Him on a wooden Cross;  8) Resurrect Him
from the grave after 3 Days and 3 Nights;  9) Exalt Him as King of Kings.

Jesus Christ of Nazareth was the Sacrificial Atonement for all humanity.

John 12:32 KJV

And I, if I be lifted up from the Earth, will draw all men unto Me (Christ).
