If you can lose your eternal life by committing unrepentant sin then that means God is an Indian giver and not true to his word. One minute you’re saved and the next minute you’re not. I thank God my salvation is secure in his hands, rather than insecure in my hands.
You’re deliberately twisting what I said. You said loving others is a work and I said loving others is a fruit. Now how about leaving the Garden of Eden and coming to the grace of the cross and empty tomb.
Believing in Christ means believing his perfect life, his death on the cross and his resurrection. It also means surrendering to him, which yes, means loving others. Loving others is not a work, it is a fruit.
