The specific words, "lose or lost salvation" would settle the issue for you, but those words are nowhere to be found. In regards to the specific words, "can't lose salvation," (Psalm 37:28, John 10:27-28; Ephesians 1:13-14) just to name a few, settles the issue for me.
I'm just showing you the hypocrisy of your argument.
What we are discussing are the concepts of these two arguments in scripture, not whether or not the specific words 'lose salvation', or 'can't lose salvation' are in scripture. Because they aren't.
