Well...you said satan tells us abiding is necessary to salvation. That abiding (remaining and growing in trust) is not necessary for a mans saving. That it scares and harms younger Christians to tell them abiding is necessary. Abiding is trusting. So...to my understanding, yes, I can name one person who has said it. But, I think it is good to take a break from our conversation when it begins to make you cross.
I had a picture to do with abiding.
I was visiting my father in law with my wife and young son. He was about 3 at the time.
We were busy talking and my slightly hyper active son was quiet sitting on the sofa.
I looked at him and so did my wife and we knew something was wrong.
The others said, no he is fine, but they did not know him.
That is abiding, knowing the moods, the ups and downs of another. It is not a question
of effort just time, listening, and being. Jesus abided in God constantly, went off to pray
alone. He was not always with the disciples, He had a quiet place and dwelt with the Father.
This is not proof of anything, this is about one thing, love and being with another. It is about
the core of who we are, what we care about and sharing this with the King. This is where His
heart is, who He is. A quiet still voice, a place of peace, a knowing and then action, when it
is right.
What you are hearing is city people, who rush here and there, worry about all their possessions
and the important things, that must be done, but Mary just sat listening to Jesus. That is
abiding, it is our lifeblood, the thing that is communion, the quiet yet profound place that others
do not enter, just you and God. You can tell a lot about a person based on their knowledge of
such experiences.
