The assurance of the believer is not that God will save him even if he stops believing, but that God will keep him believing--God will sustain you in faith, he will make your hope firm and stable to the end. He will cause you to persevere.
John PiperThe highest meaning and the most ultimate purpose of marriage is to put the covenant relationship of Christ and his church on display. That is why marriage exists. If you are married, that is why you are married. If you hope to be, that should be your dream.

John PiperThe thought of building a life around minimal morality or minimal significanceโa life defined by the question, โWhat is permissible?โโfelt almost disgusting to me.
