Counted Worthy to Escape...

Heaven and earth will pass away, but My words will by no means pass away.
 “But take heed to yourselves, lest your hearts be weighed down with carousing, drunkenness, and cares of this life, and that Day come on you unexpectedly.
"For it will come as a snare on all those who dwell on the face of the whole earth.
"Watch therefore, and pray always that you may be counted worthy to escape all these things that will come to pass, and to stand before the Son of Man."—Luke 21:33-36

These verses (34-36) appear only in Luke.  Jesus seems to be stressing the suddenness of this event and from my reading can only apply to the the Rapture.  Verse 36 tells us to watch therefore and pray always that we may be counted worthy to escape all those things that will come to pass and stand before the Son of Man.

Jesus appears to be saying that there is a real possibility that one may profess faith in Christ without possessing true faith.

Paul also reminded the Corinthians (and us) to examine themselves in regard to the genuineness of their salvation

Examine yourselves as to whether you are in the faith. Test yourselves. Do you not know yourselves, that Jesus Christ is in you?--unless indeed you are disqualified.—2 Cor 13:5

We do then need to examine the reality of our professed faith to be sure that we are trusting in the Person and work of the Lord Jesus Christ.

 I liked what Henry Morris said about this:

“The sure proof (of genuine salvation) is the realization that Christ is indwelling us by the Holy Spirit resulting in godly lives and glad acceptance of all the revealed Word of God, as inspired by the Holy Spirit.”—Henry Morris
