Jesus answered, “My Kingdom is not an earthly kingdom. If it were, my followers would fight to keep me from being handed over to the Jewish leaders. But my Kingdom is not of this world.”
All Scripture is inspired by God and is useful to teach us what is true and to make us realize what is wrong in our lives. It corrects us when we are wrong and teaches us to do what is right. God uses it to prepare and equip his people to do every good work.
