SEE, ENTER, BE BORN
From one reality into another
To see. To enter and to be born of the Spirit. These three stages speak of three births. One enters a room, but then one also exits. One ENTERS a womb and then one is born.
The process of fertilization and conception speaks of the same but in the spiritual world of God the Spirit. The entrance speaks of entering God's realm, His Kingdom a fertile place indeed. Then one matures.
Randomly we use scriptures that portray rebirth, entrance and the final birth. One becomes like wind, which cannot be controlled or defined by anyone.
As you take the time and discipline yourself to grasp all that Jesus told Nicodemus you will prepare for these three experiences, which are real. We do not deal with speculations. But there is also the final stage of which no one else knows but only you.
