That's not what scripture says. After we are led to repent by God's grace The Holy Spirit regenerates our dead spirits giving us new life from God who justifies us, giving us the righteousness of Christ. Thus we are accepted by God and forgiveness is ours on the basis of the shed blood of Christ. Being born again was a teaching well known in rabbinical literature. Every rabbi would have been familiar with it. Nicodemus would've known that there were six ways in which a man could be born again. Jesus was using terms that He knew Nicodemus would know and that's all there is to it. It was a term employed in Jewish teaching. Jesus used the same method in His parables and one of the basic rules of hermeneutics is that you never build a doctrine on a parable because it's open to too many interpretations, cults do it regularly. Every Christian is an adopted child not a begotten child, that's what scripture says. Show me a verse that says that we are begotten. You have mis-interpreted the words of Jesus by not being familiar with the background. BTW an adopted child has every right to call God his/her father or as Paul says Abba.
Jesus said that God is our Father the same as God is his Father. (John 20:17)
