 this really couldn't be any clearer. God says in Jeremiah that I will give them one heart. He'll put his spirit in them, give them one heart, and he says that they will never depart from him, nor will he depart from them in Ezekiel 36-27, where he says that I will put my spirit in them, and will cause them to walk in my statutes. Now unless someone thinks that this is speaking of only Israel, he says that he came to his own and his own did not receive them. That's Israel. But then he says, for those who received him, that is those who believe he gave the right to be called sons of God, who were born not of flesh, not of blood, but of the will of God, which is what Jesus goes on to also say in John 3 about being born again, born of the spirit. And John says this again in 1 John 5 that says whoever believes those are the ones who are born of God. And so those of us who have been born of God have the spirit of God in us. And he says that I will never turn away from them, nor will they ever turn away from me. Again, guys, this can't be any clear. We will never lose our salvation because of these passages.
