A wonderful discipleship teaching to someone wanting to understand what must be done to be saved, and to encourage another concerning the step they have taken. Another great scripture is John 3: 3-7, when Jesus explains that a person must be born again to enter the kingdom of heaven. The Spirit where ones disconnected or dead spirit is regenerated by the power of the Holy Spirit, giving the person an appreciation for the things of the kingdom and of water signifying the death of the old man and yes, an outward proclamation of having accepted Jesus Christ as Lord and Saviour.
