'Fallen' in the Bible

Then appreciate the gracious kindness and the severity of God: to those who fell [into spiritual ruin], severity, but to you, God’s gracious kindness—if you continue in His kindness [by faith and obedience to Him]; otherwise you too will be cut off.

And even they [the unbelieving Jews], if they do not continue in their unbelief, will be grafted in; for God has the power to graft them in again.
