insanity begins when one refuses to accept black and white reality, and start to make up their own.
like the Gospel- believe on the Lord Jesus Christ and you will be saved .
believe- place confidence in , entrust, to think to be true.
so, one is saved by this. the walk is a totally separate matter.
this is reality. do you accept it? or will you insist on rejecting it, and creating your own?
It strikes me that if one says this "the walk is a totally separate matter." has never met truly evil people.
A homicidal maniac who has killed loads of people comes to faith.
They continue killing people and this is not a problem?
Now this sounds an extreme example but it is the stark realities which define ones true beliefs.
The apostles were quite explicit.
9 I have written you in my letter not to associate with sexually immoral people--
10 not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters.
In that case you would have to leave this world.
11 But now I am writing you that you must not associate with anyone who calls himself a brother but is
sexually immoral or greedy, an idolater or a slanderer, a drunkard or a swindler. With such a man do not even eat.
1 Cor 5
It is clear Paul expects those who come to faith who are sexually immoral, greedy, idolaters, slanderers,
drunkards or a swindler to stop behaving like this.
So behaviour does matter, and coming to Christ creates a radical change, or else the change has not taken place.
Now one cannot really argue with this, Paul is declaring faith leads to change, and if no change is present, one
has to leave these people alone.
