“You must be born again,” was Jesus’ explanation to Nicodemus on who can see the kingdom of God.  In this day of decisional Christianity, with the emphases often being on self-will, self-improvement, and turning over a new leaf, the doctrine of regeneration is neglected, deemphasized, or all-together ignored.  The following post says it better than I ever could, so read (the post), examine (yourself), and worship (“the God who calls into existence the things that do not exist”, Romans 4:17).
