Few days ago, I had shared about Ash Wednesday. But recently I came to know that there are many more days which are observed by Christians which are hardly known by any, so here a little input on all.
Why 40 days?
The number forty has many Biblical references:
the forty days Moses spent on Mount Sinai with God (Exodus 24:18)
the forty days and nights Elijah spent walking to Mount Horeb (1 Kings 19:8)
the forty days and nights God sent rain in the great flood of Noah (Genesis 7:4)
the forty years the Hebrew people wandered in the desert while traveling to the Promised Land (Numbers 14:33)
the forty days Jonah in his prophecy of judgment gave the city of Nineveh in which to repent (Jonah 3:4).
