Check out the Lord’s words from the beginning of the third chapter of the Gospel of John:
Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews. This man came to Jesusby night and said to him, “Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him.”
Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.”
Nicodemus said 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?”
Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Do not marvel that I said to you, ‘You must be born again.’ The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.”
Nicodemus said to him, “How can these things be?”
Jesus answered him, “Are you the teacher of Israel and yet you do not understand these things? Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen, but you do not receive our testimony. If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things?”
As implied by Jesus, here, being “born again” is not something literal, but spiritual. To be spiritually born again is to be regenerated into a new spiritual being. An angel at heart. That takes time. And its a process, not an event. Here’s what Secrets from Heaven #4269 says happens during this transformation:
A person must be regenerated before he can enter the Lord’s kingdom, John 3:3; before he undergoes regeneration truth seemingly occupies the first position and good the second, but when he does undergo it order becomes turned around and good comes to occupy the first position and truth the second; also when order is turned around the Lord deploys and arranges them into order within the natural or external man in such a way that truth is there received by good and truth submits itself to good, with the result that truth is no longer the basis of the person’s action but good, that is, charity; also charity is the basis of his action when he leads a life in keeping with the truths of faith and loves what is taught for the sake of that life.
So it’s important to study scripture, think things over, talk spirituality with others, and just generally get up in your head to figure out what is and isn’t true in life. But at some point you have to move out of your head and into your heart. And that begins when you start not just thinking about what’s true but actually living what’s true.
Want to be born again? Learn the truth. Live it. And remember that truth is not the point–it’s just a vessel to hold the will for good that Jesus wants to pour into your soul. He stands at the door of your heart and knocks. All you need to do to let him in is to try your best to live a life of charity according to the true things you know. Let him in!
