Jesus tells us exactly what we must do to enter into Heaven. Eternity is where we all will exist after we die in this life. Some of us will enter into Eternity and live with the Father in Heaven. Not all will enter Heaven. It is time that we share the Good news with everyone; the Good News of Salvation through Jesus Christ.
John 3:1-20 (NASB)
1Now there was a man of the Pharisees, named Nicodemus, a ruler of the Jews; 2this man came to Jesus by night and said to Him, “Rabbi, we know that You have come from God as a teacher; for no one can do these signs that You do unless God is with him.” 3Jesus answered and said to him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.”
4Nicodemus *said to Him, “How can a man be born when he is old? He cannot enter a second time into his mother’s womb and be born, can he?” 5Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit he cannot enter into the kingdom of God. 6That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. 7Do not be amazed that I said to you, ‘You must be born again.’ 8The wind blows where it wishes and you hear the sound of it, but do not know where it comes from and where it is going; so is everyone who is born of the Spirit.”
9Nicodemus said to Him, “How can these things be?” 10Jesus answered and said to him, “Are you the teacher of Israel and do not understand these things? 11Truly, truly, I say to you, we speak of what we know and testify of what we have seen, and you do not accept our testimony. 12If I told you earthly things and you do not believe, how will you believe if I tell you heavenly things? 13No one has ascended into heaven, but He who descended from heaven: the Son of Man. 14As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up; 15so that whoever Or believes in Him will have eternal lifebelieves will in Him have eternal life.
16 “For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life. 17For God did not send the Son into the world to judge the world, but that the world might be saved through Him. 18He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of God. 19This is the judgment, that the Light has come into the world, and men loved the darkness rather than the Light, for their deeds were evil. 20For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed. 21But he who practices the truth comes to the Light, so that his deeds may be manifested as having been wrought in God.”
