The Bible tells us a lot about the new birth. The apostle Paul tells us that if anyone is in Christ, is a new creation, old things has passed away and all things has become new. Jesus also speaks to Nicodemus telling him that it is necessary to be born again. To be born again is to become a new person, casting aside what we were before and immersing ourselves in the will of God.
We who are in Christ are no longer the same people, so I have always held the idea that the only place where we can be transformed from the worst person to a different person is in the arms of our beloved and King Jesus Christ.
