The Christian Faith (Roman, Eastern, and Protestant Traditions) have viewed the actual return of The Lord as a matter of settled doctrine, and it is affirmed in the Historic Creeds of the Church ("He shall return to judge the living and the dead...") What becomes issue is the idea if "date setting", especially in the light of Christ's own words. The Master declared that "No one knows the day and the hour that the Son of Man will return." Perhaps more importantly, this statement was preceded by the exhortation to "Watch and Pray" that the hearer would be prepared and not caught unaware when the Master manifests himself.
"We need not fear the fictitious Planet X. But we need to admit the reality that we are one day closer to eternity than ever before. And we have only today to be ready". -- Jim DenisonCommentator and author, Jim Denison,shares his thoughts on this latest Rapture prediction in today's Denison Report, which is linked here.
My personal thoughts on this are pretty simple. Each Sunday I, along with millions of my best friends, affirm the truth of Christ's return. There is nothing to stop that return on any given day and the nanosecond the Father commands it, the event will be set into motion. And, given the fragility of human life, an accident, sickness, or sudden medical mishap could irrevocably propel me into His presence. For me, this is the "watching" part of the exhortation, which is why, in-turn, I pray to be found faithful in each new day.
