Yes.
If I kill someone who is trying to murder someone in front of me, man and his court does not prosecute me. God would also know I was risking my life in defense of another, which is not condemned by God in his word, and as such I would remain saved.
There are junkies who were and are Christian. They have a lapse on the way but that doesn't mean God turns from them. If anything, that is when they need God the most.
As I read it, verses that tell us God will turn away from us, or that passage that says , if we deny Jesus he shall deny us, are not saying, God will strip away our salvation. Our salvation is eternal life through Christ our Lord. It isn't something we find out about, if we passed the mortal test, to achieve the salvific promise while on earth. Rather, again as I've read it, we are saved the moment we accept Christ as our savior. Savior=Salvation=Saved. Jesus said, no one can take us from his hand. If no one on earth can do that, then Jesus shall not either. Or else he would have worded the scripture to read, no one can take you from my hand but you are able to release my grace filled covenant if you choose.
That would make us able to out-know God, since he knows who are his sheep and those who will at the judgment argue they did this and that in his name, i.e. as professing Christians, yet he does not know them.
People who lose their salvation, in my view, are those type people. Those who were never part of the actual covenant. We can't fool God. While fake Christians abound.
