God - the One and Only Creator - is a holy, just, loving and merciful God. Of utmost importance is his quality of holiness because holiness is a defining element of God’s character. Therefore as children of God, the defining element of the character of everyone entering the Kingdom of God must be holiness. Since we are born in sin and shaped in iniquity, we must be born again to a new life of holiness in order to enter the Kingdom of God, as it is written in John 1: 5-7:

“This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all. If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth. But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.”

According to God’s requirement, we must be born of water and the Spirit to enter the Kingdom of God. 

What does this mean?  How is it accomplish?

Born of Water

John the Baptist came baptizing people unto repentance in accordance to God’s will. It was John the Baptist who baptized Jesus Christ in the River of Jordan. After Jesus Christ’s resurrection and just before he left to return to Heaven, he instructed his disciples to baptize those who believed in him, as it is written in Matthew 28: 18-20

“And Jesus came and spoke to them, saying, "All authority has been given to Me in heaven and on earth. Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age." Amen.”

Please be aware of the necessity of full body submersion in water baptism. It is not the sprinkling of water or merely the wetting of one's head with "holy" water. Throughout the New Testament, water baptism is described as one being submerged under water and then being raised back up. What is the significance of water baptism? Water baptism symbolizes our death with Jesus Christ, as it is written in Romans 6: 3-13:

"Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.

For if we have been united together in the likeness of His death, certainly we also shall be in the likeness of His resurrection, knowing this, that our old man was crucified with Him, that the body of sin might be done away with, that we should no longer be slaves of sin. For he who has died has been freed from sin. Now if we died with Christ, we believe that we shall also live with Him, knowing that Christ, having been raised from the dead, dies no more.

Death no longer has dominion over Him. For the death that He died, He died to sin once for all; but the life that He lives,

He lives to God. Likewise you also, reckon yourselves to be dead indeed to sin, but alive to God in Christ Jesus our Lord. Therefore do not let sin reign in your mortal body, that you should obey it in its lusts.  And do not present your members as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God."

Born of the Holy Spirit

What is the significance of the Holy Spirit and why is it so necessary to be born of the Holy Spirit? Jesus Christ reveals the significance of the Holy Spirit, as it is written in John 4: 23-26:

"But the hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for the Father is seeking such to worship Him. God is Spirit, and those who worship Him must worship in spirit and truth."

The woman said to Him, "I know that Messiah is coming" (who is called Christ). "When He comes, He will tell us all things."

Jesus said to her, "I who speak to you am He."

What’s the purpose of the Holy Spirit and what part does he play in one’s entering the Kingdom of God? As products of the world of darkness, we are the antithesis of those who enter and live in the Kingdom of God. How do we become that which we are not and know not? We are flesh, God is spirit, we are born and live in darkness, God is and has always been holy. How do we do it? We cannot but God can. How does He do it? How does God make us into what we are not?  God does it through the crucifixion and resurrection of Jesus Christ which we symbolize via water baptism and the working of the Holy Spirit within us, as it is written in John 14: 15-17; 23-26

"If you love Me, keep My commandments. And I will pray the Father, and He will give you another Helper, that He may abide with you forever - the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you.

Jesus answered and said to him, "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him. He who does not love Me does not keep My words; and the word which you hear is not Mine but the Father's who sent Me.

"These things I have spoken to you while being present with you. But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you. Peace I leave with you, My peace I give to you; not as the world gives do I give to you. Let not your heart be troubled, neither let it be afraid."

In conclusion, the Word of God says in Romans 8: 1-14:

“There is therefore now no condemnation to those who are in Christ Jesus, who do not walk according to the flesh, but according to the Spirit. For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death. For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin:

He condemned sin in the flesh, that the righteous requirement of the law might be fulfilled in us who do not walk according to the flesh but according to the Spirit. For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit, the things of the Spirit. For to be carnally minded is death, but to be spiritually minded is life and peace. Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be. So then, those who are in the flesh cannot please God. But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His

And if Christ is in you, the body is dead because of sin, but the Spirit is life because of righteousness. But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you. Therefore, brethren, we are debtors--not to the flesh, to live according to the flesh. For if you live according to the flesh you will die; but if by the Spirit you put to death the deeds of the body, you will live. For as many as are led by the Spirit of God, these are sons of God.”
