" What does it mean to persevere? It means that we continue to believe, and that we live like believers, which means obediently. It doesn’t mean sinlessness; it doesn’t mean that we are on some steady and never-failing incline up into pure sanctification; it does not deny stumbling or messy spirituality; it doesn’t deny doubt and problems. It simply means that the person continues to walk with Jesus and doesn’t walk away from him in a resolute manner. "
