The Bible passage which refers to being born again can be seen here.

We must be born again in order to "see" or perceive the kingdom of God. We are first born in the flesh as human beings with a body and a soul. But in order to be born in the spirit so that the Holy Spirit can come inside us, we must be "born again." This means that we must recognize who Jesus was and is-God`s Son. And we must recognize that we need Him to be our savior and our Lord.

We need to realize that we have done wrong things (sins) and that we are far from God. Then we need to accept that Jesus died for our wrongdoings on the Cross at Calvary. Once we accept these things and believe in Jesus as God`s Son, we can invite Him into our heart to be born again.
