Born again of water by water baptism in the name of Jesus

When I am baptized in the name of Jesus, I am born again of water. 

"Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God." - John 3:5 

When Jesus said we must be born again of water, Jesus was not talking about the water that comes out in a natural birth. He was talking about being born of water in a spiritual birth. Jesus said, we must be born AGAIN.

"Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born?" - John 3:4 

Jesus answered Nicodemus,

"That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. Marvel not that I said unto thee, Ye must be born again." - John 3:6-7 

I must be born of water and of the Spirit in order to enter into the kingdom of God.

I am born of water when I am water baptized in the name of Jesus.

Jesus gave Peter the keys to the kingdom.

"And I will give unto thee the keys of the kingdom of heaven…" - Matthew 16:19 

Peter preached the keys to the kingdom on the Day of Pentecost. Peter preached how to be born of the water and of the Spirit and the door was opened to the kingdom.

"Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost." - Acts 2:38 

That day, those that received his word were born again of water and of the Spirit.

"Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls. And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers...And the Lord added to the church daily such as should be saved." - Acts 2:41-42, 47
