You can come to the end of the road, come to a conclusion, or invite friends to come to your party. Come generally means to move along purposefully toward something.
Come (came in the past tense) can also mean "happen," as in the Christmas carol that begins "It came upon a midnight clear..." or the old-fashioned phrase "it will come to pass," which means "it will happen." When you're counting up your purchases at the convenience store, you might say "two apples, five oranges, and a candy bar — that comes [adds up] to $4." If you were born in Ohio, you'd say you come from Ohio.
