The lesson was based on a talk from April 2008 general conference.
Elder D. Todd Chistofferson - Apostle (Audio, Video)
The instructor cited the story that Elder Christofferson related about having a retired protestant minister come to his home because the minister was concerned about Elder Christofferson's salvation. He and the minister had talked about what it meant to be born again.
Unless we put off the natural man we have not come to Christ. Does this mean we are perfect and do not make mistakes, but if we have put off the natural man we constantly reach for Christ and strive to do better.
- 19 For the anatural bman is an cenemy to God, and has been from the dfall of Adam, and will be, forever and ever, unless he eyields to the enticings of the Holy fSpirit, and gputteth off the hnatural man and becometh a isaint through the atonement of Christ the Lord, and becometh as a jchild, ksubmissive, meek, humble, patient, full of love, willing to submit to all things which the Lord seeth fit to inflict upon him, even as a child doth submit to his father.
Being born again is a process and not a one time event.
