It is really interesting to read what people do in order to start a new year on a clean slate.
They know that they are sinners.
As a symbol of tossing away their sin, they throw breadcrumbs into the water (river).
That is the ancient Jewish custom of Tashlich.
In the magazine Israel and Christians today, New Zealand October 2015, is a picture of UN chief Ban Ki-moon and Israeli envoy Ron Prosor casting their sins into Turtle Bay. The article is called “ECI Co – Hosts First Ever Tashlich Ceremony at the UN.”
In his book UNTO THE HILLS Billy Graham writes also about “a clean slate,” and he says that God is wiping our slate clean when we are coming to Him and when we are confessing our sins.
In First John 1:9 the Bible says:
“If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.”
