WRITING DOES NOT CHANGE HEARTS

If our writings in themselves good change the hearts of men, then we should dismiss all our armed forces and assign them to publishing houses, mailing books to the enemy in WWI, WWII, Korean War, Vietnam War, and such; If the book did not convince the leader, then surely reduce their forces in half. Christians march in peace and peacefulness, knowing the King shall come with a sword out of His mouth, and the blood shall rise to the horse's bridle.

Rev 6:15 Then the kings of the earth and the great ones and the generals and the rich and the powerful, and everyone, slave5 and free, hid themselves in the caves and among the rocks of the mountains,  16 calling to the mountains and rocks, “Fall on us and hide us from the face of him who is seated on the throne, and from the wrath of the Lamb,  17 for the great day of their wrath has come, and who can stand?”
