This is the new life that enables us to live as a Christian should. We see then that being born again means to spiritually die symbolically be buried Ghost. Thus, in plain language an individual must repent of his sins, be baptized into the name of Jesus Christ by immersion, and receive the gift of the Holy Ghost. This was for cleansing of the nations. It takes blood and water to eradicate sin.
Blood is the cleansing agent, and water is the flushing agent.
When a jar is washed for canning, soap AND water are necessary to cleanse that jar so that it might be filled with good fruit. Likewise, blood and water are necessary to cleanse the human soul so that it may receive the spirit of Christ which is the Holy Ghost. Paul taught that the three steps of Calvary was the gospel that we should preach. Paul told us that the gospel is the death, burial, and resurrection of Christ. Ghost as we have previously explained.
