Christ's ONE sacrifice is sufficient to cleanse us of ALL unrighteousness. We are born of the spirit ONE time, not multiple times.
Let me talk about washing up after a meal. Each plate, knife, fork, spoon, glass, needs to be cleaned.
Each time it is washed it is cleansed. The one washing cleanses away all dirt.
But it does not purify the heart so it cannot defile the person again. It does not remove the possibility
of sin, or the habits that lead to sinful behaviour.
The temple and sacrifices are because people sin knowingly and unknowingly, it is an on-going issue
even with a dedicated spirit and obedience. But each time when conviction comes, repentance,
confession and going to God things are put right. This is how relationships work, with moods,
reactions, changes of direction, ups and downs. And God provides a way of cleansing, staying pure,
walking in righteousness. And the more you walk, the more likely you will not stumble or have
problems, the better you cope and the more consistent it all becomes.
And yes if people give up, abandon the walk, disavow Christ, there is a breaking of the relationship.
But the prodigal son may return, the foundation maybe returned to and not left alone.
I have a christian brother who did these very things. It took a year and he returned to walking with
God. The language is a warning, things need to be walked in to be real, this is not a mystic bought
in never lost deal. This is real friendship and understanding the eternal principles of creation and
the creator.
Once you know them, you have a choice, walk in them or go back to blindness and delusion.
