Again is Imla.Again?
Christ was never formed in some of the Galatians to begin with Derrick:
“My little children, of whom I travail in birth again until Christ be formed in you” (Galatians 4:19)
“Again” is not in the text.
Paul is speaking to Christians at Galatia, that are removed to another gospel, that did run well.
I don't agree with the OSAS excuse, that every Christian returning to sinning, was never saved in the first place.
