Can Someone Stop Being Christian?

Brothers and Sisters in Jesus Christ:
Humpty Dumpty sat on the wall. Humpty Dumpty had a great fall. Not all the king's horses, nor all the king's men, could put Humpty Dumpty together again.

If you understand this nursery rhyme, you can understand this passage – a passage that appears to say someone can stop being a Christian.

Our headings are:

1. The Believer is Saved, Sanctified, and Secured Forever
2. How Come It Appears He Can Lose His Salvation here?

Our goals are:
That you will be forever thankful God has secured you for eternity through the glorious work of the Savior and you will make every effort to make your calling an election sure.
