Jesus tried to explain the fact to Nicodemus that one must be born again to enter the Kingdom of God. We read about this in John 3:1-7:
“There was a man of the Pharisees named Nicodemus, a ruler of the Jews. This man came to Jesus by 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 and said to him, ‘Most assuredly, 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, ‘Most assuredly, 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.”’”
Nicodemus missed the whole point and was only thinking in physical terms, while Christ was speaking in spiritual terms. Since Nicodemus did not have God’s Spirit at that time which would have helped him to understand spiritual concepts, he just did not get it, which is made obvious by his response in verse 4 (“How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?”).
When it comes to human reproduction, the human egg is incomplete. It must be fertilized by the sperm of a man. Then, an embryo will grow in the mother’s womb. In time, the embryo becomes a foetus which is fed and protected in the womb. It grows to full term until it is born into this world.
While in the womb, the baby exists in darkness, but it is protected and nourished. Once in the world, the baby has entered a realm of light, but it still needs to be fed and taken care of.
God gives each baby a spirit at the time of conception. But even with the human spirit within him, a man is still incomplete. In order to be able to ultimately enter the spirit realm and become a Spirit being, he must first receive God’s Holy Spirit upon repentance, belief and baptism. At that time, he becomes a begotten child of God; he is not born yet. But even with the receipt of the Holy Spirit as a “down payment,” the spiritual mother–the Church of God–has still the responsibility to feed God’s begotten children spiritually and to protect them from the negative influences of the god of this world, Satan the devil. But it is also important that God’s begotten child is willing to be nourished by his or her mother.
Once a person has achieved the necessary level of spiritual maturity, as determined by God, he can enter into the Kingdom and Family of God as a born-again child of God at the time of Christ’s return, not prior to that. He will be changed into a Spirit being and enter the spirit realm. For those who are called in this day and age and have received God’s Holy Spirit, their transformation and change will occur when Christ returns. Others will be called after Christ’s return to obtain the same opportunity.
That is our human potential.
The transition into the spirit world will be much more dramatic than at the time when a baby is born into the physical world. We will enter a world of light with opportunities that we can hardly imagine. What a glorious future lies ahead for those who remain faithful to the end! As Paul stated, the trials of this world are nothing in comparison to the glory that awaits us in the Kingdom of God.
Let’s ensure we keep our eye on the goal and remain faithful to our calling.
