What Borg is teaching is not what the scriptures teach. Jesus said "I am the way" it is through Him that we come to the Father, not just by his teaching. He also said in John 3:6 Flesh gives birth to flesh, but the Spirit gives birth to the spirit. 7 you should not be surprised at my saying. "You must be born again" Borg's teaching is not Christianity.
Christianity teaching a holy life which is enabled by The Holy Spirit. Sorry but Borg rambles on with his own interpretation. If you want to know the truth read the New Testament and ask for the Holy Spirit to reveal the truth to you.
