Sorry I did not really understand "the cup" part. Maybe you are speaking about some verses I do not remember now. For me the water is the water, and the cup is the cup.

We Christians are to be of one mind, especially in matters of faith:
"Fulfil ye my joy, that ye be likeminded, having the same love, being of one accord, of one mind." (Philipians 2:2)

The Bible is clear in that we are indeed saved by faith, but not faith alone, because faith without works is dead.
And we are NOT saved by works alone, faith is absolutely necessary. But it will be rendered to each according to their works. To some glory and honor and to others wrath.

“He will render to each one according to his works: to those who with endurance in well-doing seek for glory and honor and immortality, he will give eternal life; but for those who are self-seeking and do not obey the truth, but obey unrighteousness, there will be wrath and fury” (Romans 2:6-8).
