Can you actually Lose Your Salvation?

From John 10:22-42-Have you ever wondered if you could lose it; not your keys, but your salvation? Jesus gets asked a version of that question in today's passage, and for once, he answers it as plainly as he ever does. Cornered at the Festival of Dedication by a crowd demanding a straight answer, Jesus gives them one: his sheep hear his voice, he gives them eternal life, and no one will snatch them out of his hand. Then he closes the loop with a sentence that gets him nearly stoned; 'I and the Father are one.'
