Hi, Wynand and Rocky. Reading Matthew 12:40 , Jesus predict a that as Jonah was three days and three nights in the belly of the great fish, so will the Son of Man be 3 days and 3 nights in the heart of the earth...We traditionally celebrate the crucifiction on Good Friday. However, the math does not make sense if Jesus was raised on the Sunday. Can you please shed some light on this?. Thank you, Johan.
