Hi and 1 Peter 1:23 is for today , explain 2 Peter 2:9 and how can a person be BORN AGAIN ??
DAN P
Yes, I Peter 1:23 is for today.
I John 4:13 tells us what that incorruptible seed is, it is that which God gave to us of, His spirit.
As for your question, did not Nicodemus ask that same question?
What did Jesus tell him?
John 3
9 Nicodemus answered and said unto him, How can these things be?
10 Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things?
11 Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
12 If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
15 That whosoever believeth in him should not perish, but have eternal life.
That is how Jesus answered Nic's question.
In the gospel, while Jesus' ministry for our redemption and salvation was a work in progress, the answer would be different than after he finished his works.
Today, in this age of grace, the gift of salvation/eternal life/incorruptible seed is received by doing Romans 10:9-10
