Can Someone Lose Their Salvation?

Can A Saved Person Lose their Salvation A Riddle:
It is a riddle more than a question. There is ample biblical evidence to support both sides of the debate, but do to a lack of congruent spiritual wisdom and understanding people have trouble grasping the true answer to the riddle. The correct answer, of course, is that a saved person, who is “truly saved“, can NOT lose there salvation. But here is the dichotomy: Who is truly saved? Can we judge that in another person. NO! We can only judge the surface of human behavior. We are not God.
If someone has absolutely no character change and continues to lie, gossip, who is habitually careless and reckless about their sins, has no inclination to repentance, then how can that person even suggest or believe that he or she is saved?
The riddle of salvation is not whether a person can lose salvation or not, but whether or not “True Salvation” has taken place. Many have deceived themselves into thinking that they are saved, all the while they willfully continue living in sinful rebellion.
