Revelation 22:17

17 And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.

The first part of the verse where the Spirit and the bride says, "come" may be asking Jesus to hasten His return to earth. The Spirit in the bride in effect says we are ready for you Jesus, come to earth. I suppose the Spirit and the bride could also be asking people to come to drink but since there is another "come" later in the verse for the thirsty it would appear to be redundant. Since the Spirit in the Bride would say both things. You cannot go wrong with either viewpoint.

In any case, it is clear the rest of the verse is directed at those that are thirsty. We are told the water of life is given freely to all that are thirsty for Him (Jesus). The words  and whosoever will  seems to indicate that mankind has free will of choice to come to Jesus to be saved or not.
