Passover as a way to understand Good Friday

There are many links between Passover and Good Friday. The lambs that were slain every year at Passover (when Israel remembered: not at all often in the 500 years when Kings ruled over Israel - maybe about ten times in that period!) were a pointer back to the great salvation achieved in Exodus and a pointer forward to the far better salvation when the true Passover Lamb, God's own Lamb, was slain for many to go free. Likewise the death of Jesus was full of things that would make Jewish readers think back to the Passover, in order to help them understand what went on.

Firstly, Passover:

God wanted to redeem a people from slavery (Ex 3:9, 20:1) so they could worship him. (Ex 5:3)
So he sent judgement on the slave-master, Egypt. (Ex 11)
This judgement was deserved by the people whom God was saving, the Israelites. (Ex 13:11-15)
So God told them to kill a lamb in the place of those who should die as judgement from God. (Ex 12:6)
God's judgement 'passes over' those places which the door is covered by lamb's blood. (Ex 12:23)
This brings the nations to worship God (Ex 12:38)

And the Good Friday parallels:

Christ died on the day of the Passover (Jewish days are sunset-sunset, the Passover was eaten the evening before, and the day afterwards was the Sabbath, which followed Passover). (Luke 22:7)
God wanted to redeem a people from slavery so they could worship him. (Rom 6:17-18)
So he sent judgement on the slave-master, sin. (Rom 8:3)
This judgement was deserved by the people whom God was saving, the Christians. (Rom 5:8)
So God killed the Lamb in the place of those who should die as judgement from God. (1Cor 5:7, Mark 10:45, Rev 5:9)
God's judgement 'passes over' those people who are washed in the Lamb's blood. (Rev 7:14, Rev 12:11)
This brings the nations to worship God (Rev 7:9-10, Acts 11:18, Eph 2:11-13)
