And that union cannot be threatened, even by ongoing failures. It was God, not me, who united me to him in the first place. It is God, not me, who is alone capable of un-uniting me from him. And because justice has been satisfied, God never will. Jesus would have to be pulled down out of heaven and put back in the tomb in order for me to be dis-united from him. (John 10.28-29)

28 I give them eternal life, and they will never perish, and no one will snatch them out of my hand. 29 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. (John 10:28-29)
