'Backslidings' in the Bible

“Your own wickedness will discipline you,And your desertion of the faith will punish you.Know therefore that it is an evil and bitter thingFor you to abandon (reject) the Lord your God,And for you to be indifferent to Me and dismiss the [reverent] fear of Me,” says the Lord God of hosts.

Therefore a lion from the forest will kill them,A wolf of the deserts will destroy them,A leopard is watching their cities.Everyone who goes out of them shall be torn in pieces,Because their transgressions are many,Their desertions of faith are countless.

“O Lord, though our many sins testify against us” [prays Jeremiah],“Act now [for us and] for Your name’s sake [so that the faithless may witness Your faithfulness]!For our backslidings are countless;We have sinned against You.

They will no longer defile themselves with their idols, or with their detestable things, or with any of their transgressions; but I will save them from all their transgressions in which they have sinned, and I will cleanse them. So they will be My people, and I will be their God.
