"...the gifts and the call of God are irrevocable."
Psalm 69:30-31, 33-4, 36
I'm an avid fan of the procedural show "Bones". I'm fascinated by how brilliant scientists can find the truth in 206 bones in the human body. In one of the episodes, an intern was fairly hyped at the thought that he was going to have his first work published in a leading scientific journal. True, he only had a page proof--a near final version for printing--but you can see he's bursting at the seams with pride.
For scientists like him, the approval of his peers--as seen in his soon-to-be-published work--tells him he's arrived. He's become part of the "in" crowd.
Then his work got shuttled and somebody else's work got published instead. Between the page proof and the final publication, he lost the honor. Of course, by slips of his and his friends and family's tongues, the revocation of that top honor suddenly turned into an embarrassing, humiliating and utterly mortifying experience.
From the tops to the dregs in one fell swoop. Just because someone took back the invitation to be "in".
Unlike the intern's predicament, God's call--the invitation to become part of the saints in Heaven where He is, and the gifts that go with it--is irrevocable.
