Can a born again believer lose salvation?

If you have never had salvation in the first place, that is the only way to lose it. While you may have experiences, doctrine, or religion, without true faith in Jesus Christ, salvation cannot be attained. It is false to suggest that all born-again believers lose their faith or salvation, as this would contradict what Jesus stated in John 10, and we know that God can never lie. Believing in what God has said would become meaningless if one sin could cause us to be forsaken after we have believed, trusted, and obeyed Him.
