The duty of the true Christian is clear and plain. Whatever others do, he must give all diligence to make his own calling and election sure. While others are occupied in national conflicts and political speculations, he must steadily seek first the kingdom of God. In so doing, he shall feel his feet upon a rock when the foundations of the earth are out of course, and the kingdoms of this earth are going to ruin. He shall be like Noah, safe within the ark.
