John 10:26-30

but you do not believe because you are not among my sheep. My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me,is greater than all, and no one is able to snatch them out of the Father’s hand. I and the Father are one.”
