Hi Edith, this was probably an answer to a question that you asked or pondered upon. It speaks of someone being inspired by the Holy Spirit (water) to organize. The hands of a person symbolize the power and organizational aspects of the body of Christ. It is all about power (opportunity and ability) to bring into existence (organizing, functioning, and handling of spiritual issues in the body of Christ).
Ephesians 5:26 That he might sanctify and cleanse it with the washing of water by the word (the word is the backbone of this person or ministry). The color white in dreams and visions symbolizes victory or holiness or righteousness or faith.
