So, Brothers and Sisters, if we can say that we love God’s people, as God’s people, because they are God’s people, that is a mark that we have passed from death unto life! Do you love them for Christ’s sake? Do you say to yourself, “That is one of Christ’s people. That is one who bears Christ’s Cross. That is one of the children of God and, therefore, I love him and take delight in his company”? Then that is an evidence that you are not of the world. If you were, you would love the world, but, belonging to Christ, you love those who are Christ’s and you love them for Christ’s sake.
