Is it possible, in any way shape or form, to lose one's salvation once that person has accepted Christ?
In my opinion, the answer is no. If someone has TRULY accepted Christ, then their heart will drive them toward good works and a desire to rid their lives of their sinful nature. But once we accept the sacrifice that Jesus made, our sins are forgiven, both past and future, and we are children of the Lord. The Holy Spirit will drive us to better ourselves, to fight the sin in our lives, and to reach out to others in His loving image rather than our old sinful selves.
I've heard it said that if you are saved and continue to sin, you will no longer be saved. To me, that's absolute rubbish. No one is perfect. No one, aside from Jesus, as ever been perfect, and no one else will ever be perfect. We are all sinners, saved or not. If it were true that sins could cause us to lose salvation, then salvation wouldn't exist.
HOWEVER, there is a distinction I must make.
Salvation through Christ is not a license to sin. We cannot say, "Well, I can do whatever I want, because God has forgiven me." That kind of mindset indicates that the person does not truly respect or understand what Christ did for us, and therefore did not truly accept Christ's guidance into their lives in the first place. Those people, I believe, were never saved, because they didn't accept every aspect of a relationship with Christ, they tried to get away with taking only what they believed they needed to get into heaven.
