"Picture a large circle, from the edge of which are many lines all running to the center. The nearer these lines approach the center, the nearer they are to one another.
Thus it is in the Christian life. The closer we come to Christ, the nearer we shall be to one another. God is glorified as His people unite in harmonious action.”
“The cause of division and discord in families and in the church is separation from Christ. To come near to Christ is to come near to one another. The secret of true unity in the church and in the family is not diplomacy, not management, not a superhuman effort to overcome difficulties—though there will be much of this to do—but union with Christ.”
Those excellent quotes are from a book called Adventist Home, page 179, where you can read much more about how to have a loving home.
You can also study a lesson at this link that will help your family have greater harmony.
When something comes up that makes you feel distant from a family member or friend, what will you do to press closer to Jesus that will then hopefully lead you closer to that person?
