You can use the "Keep lines together" option for paragraphs; it'll force all the lines of a paragraph to display on the same page. You'll find the option on the Line and Page Breaks tab of the Paragraph dialog box. To open the dialog box, select the text, right-click, and choose Paragraph on the context menu.

Of course you can modify the paragraph style you are using to include the setting. In the Modify Style dialog, click Format, and then click Paragraph.
