THERE IS NO SUCH THING AS A MAN CANNOT SIN, AS LONG AS YOU ARE ALIVE YOU CAN SIN, THIS IS WHY JESUS HIMSELF ESTABLISHED HIS ROMAN CATHOLIC CHURCH AND HE GAVE THEM THE SEVEN SACRAMENTS EVEN BEFORE HIS CHURCH FORMED THE FIRST FULL BIBLE. SEE HERE TRUE MEANING OF BORN AGAIN AND THIS IS JESUS HIMSELF TALKING
 This man came to Jesus by night, and said to him: Rabbi, we know that thou art come a teacher from God; for no man can do these signs which thou dost, unless God be with him.  Jesus answered, and said to him: Amen, amen I say to thee, unless a man be born again, he cannot see the kingdom of God.  Nicodemus saith to him: How can a man be born when he is old? can he enter a second time into his mother's womb, and be born again?  Jesus answered: Amen, amen I say to thee, unless a man be born again of water and the Holy Ghost, he cannot enter into the kingdom of God.
BORN AGAIN IS BEING BAPTIZED, BECAUSE IT ERASES ORIGINAL SIN FROM OUR SOULS. FOR WE INHERITED ORIGINAL SIN NOT KNOWING OF IT, THEREFORE GOD ERASES IT FROM OUR SOULS WITHOUT KNOWING IT ALSO, THATS WHY CATHOLICS BAPTIZE BABIES.
PROTESTANTS THINK (WRONGLY) THAT IT HAPPENS WHEN ONE TURNS TO JESUS AND SEEKS FORGIVENESS, IT IS THE SAME GOOD FEELING CATHOLICS GET WHEN THEY GO AND COMPLETE THEIR CONFESSION TO A PRIEST. THEIR SOULS ARE WIPED CLEAN FROM THE STAIN OF SINS WHEN SINCERE AND HUMBLE OF HEART. THEY THINK THAT IS BORN AGAIN, BUT THIS IS NOT TRUE, YOU STILL HAVE TO BE BAPTIZED TO GET INTO HEAVEN AND IT MUST BE WITH WATER, AND IN THE NAME OF "THE FATHER, THE SON AND THE HOLY SPIRIT. OR YOU WILL HAVE TO BE BAPTIZED ALL OVER AGAIN IF NOT DONE THIS WAY, JESUS HIMSELF STATES THIS IN THE HOLY BIBLE.
