The Meaning of Good Friday
Good Friday celebrates what we believe to be the most momentous weekend in the history of the world. Ever since Jesus died and was raised, Christians have proclaimed the cross and resurrection of Jesus to be the decisive turning point for all creation. Paul considered it to be “of first importance” that Jesus died for our sins, was buried, and was raised to life on the third day, all in accordance with what God had promised all along (1 Corinthians 15:3).
On Good Friday, we remember the day Jesus willingly suffered and died by crucifixion as the ultimate sacrifice for our sins (1 John 1:10). The Sunday after Good Friday is Easter, the glorious celebration of the day Jesus was raised from the dead, heralding his victory over sin and death and pointing ahead to a future resurrection for all who are united to him by faith (Romans 6:5).
