Rev.22:16 I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
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.

who was this written to? THE CHURCHES
These are people that are able to hear.

all this verse proves is the ignorance of the freewiller to read the context surrounding the verse they pull out to prove a point.
