Jesus came so as to fulfill a prophesy that had been promised by God. Though he was the only Son of God, he lived and obeyed all the ways of the Jews so that he would live as an example to the rest of the world.

i will forever be grateful for the sacrifice he e devoured so that i could be saved. There is completely no suffering that can equal what he went through. 

All in all he was our saviour from all our sins,
