David said: You don't need to know the correct nomenclature, to know that the light has been switched on inside you, that Jesus took your sins and punishment on the cross, that you are forgiven and that you now love Jesus and want to follow him. This is what happens when one is born of God; and it happens immediately.
David, one must at least understand meaning of regeneration based upon Jesus' teaching in John 3 to call this experience regeneration, when it very well could have been a beginning of conversions to the truth, when either age, or hearing the gospel for the first time, (
with their new ears, and eyes and a heart to receive) or even witnessing the gospel being lived out in submission to the truth, which we have scriptures to support all three.
Regeneration gives a child of God
the power to hear, see, understand, even though at first, they are only able to received the milk of the word, not meat.
Example would be helpful:
Matthew 27:44
“The
thieves also, which were crucified with him,
cast the same in his teeth.”
At the beginning of our Lord's death on the cross,
both malefactors mocked Christ, but at some time into this crucifixion one was regenerated and yes, immediately began to show forth fruits, yet he had no understanding of what had taken place within him by the power of God, we only see the results of this change in our own life, just as we can see in Nicodemus' confession in John 3:2
David: Have you ever experienced it?
Much like Nicodemus did, and conversion was a very small process (baby steps if you will) over a few years, I'm sure others have a different testimony. But, all of us should be close, as far as conversion goes.
David: You don't need to know the right words to know that you have new life inside you and have been forgiven because Jesus died for you.
David, one is dead in trespasses and sins, he
must be resurrected to life by the power of God, and then, and then
only, will he begin to show forth life, not necessarily as an some saints would desire, but patience is require so that that new life is not offended, and we be guilty of offending one of God's little one. Maybe more later.
