The Easter story is a very important part of God’s plan for the salvation of the human race. Salvation means saving, in particular saving people from the consequence of their wrongdoing or sin. I touched on this in my post for the Letter O, Offering.
Jesus Christ (Letter J) came to be the saviour (savior or redeemer, Letter R) of the world. Luke 2:10-12 His death (Letter D) made this possible. However salvation is not automatic. It is a gift, which is offered, but has to be received and lived out to provide any benefit. Philippians 2:12-13 An earlier A to Z post of mine was about Saviour.
Simon of Cyrene is only mentioned in the Easter story. He was caught up in the events without any choice. Jesus had been arrested, tried, sentenced, tortured and was on his way to Golgotha (Letter G), the site of his crucifixion. He had been forced to carry his own cross, but collapsed under its weight.
