12 “I have many more things to say to you, but you cannot bear them now. 13 But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come.
This particular point is not water baptism, which follows and signifies the reality of this work of the Spirit already having occurred in conversion. Water baptism is a God ordained picture that re-enacts and illuminates the new believer to the truth of what happened to them at salvation. People don't get water baptized to get saved and spirit baptized, rather they are water baptized following their salvation. Water baptism logically connects the new Christian back to the reality of their prior spirit baptism, however it does not impart the salvation which it pictures or points. In the death, burial, resurrection sequence of believer's baptism by immersion, the Christian acts out in sign form the Spirit's uniting of them to Jesus Christ which occurred in His spiritual baptism or uniting of them to Christ at prior saving faith.
