You must be born again ( John 1 v 9- 13)

In John 3 v 7 our Saviour said ,'You must be born again',what did He mean by these words, Jesus spoke these words to a very religious Jew,and yet he did not understand what Jesus said.Jesus is talking about the vital importance of a spiritual birth,He is saying as you been born naturally so one needs to be born spiritually.If we are not born spiritually we cannot have a relationship with God unless we are born again,we are shut out from Him,we are not God's children.We may be very religious but that does not count,you may be a minister and you may have not been born again. If  you are not born again you are lost,you may have been baptised as a child as I was,but that does not make you a Christian,baptisim can save no one,baptisim is for believers,it is an open declaration of what  Christ has done for us. John the baptise,baptised people with water, he spoke of one who would baptise with the Holy Spirit. (John 1 v33) In 1 Corinthians12 v13 we read ,'we have all been baptised into one body by one Spirit',this is speaking of when we become a Christian when by faith we ask Jesus to be our Saviour.
