Tense is about time - past, present and future. Verbs have forms that tell us what time they are referring to: those forms are what we call tense. So the Future Tense means the verb is telling us what someone will do or what they are going to do, what will happen or what is going to happen. The Future is really easy in German, and so there's only one resource that will sort everything out for you really quickly.
