The ELECT don't reject the message of God. Merely being baptised or reciting the sinner's prayer does not make one of the elect. It is only the first step in our walk with Christ, our new birth spiritually. But one can turn away and return to his old life, return to the vomit. There is NO WAY a person here on earth can know he is of the elect without a special grace from God - which rarely comes to the saints. The ordinary work out their salvation in fear and trembling - hoping that we ARE of the Elect, but not knowing until the end.

Well put.
