Tis been "my" experience, that I hadn't even realized that had been done, Until I was "shown", that I had! And "that" wasn't until later on, after I "answered" the call! And, later realized that "answering the call", wasn't even one of the options!...LOL!....
I remember a good 3 er 4 times, probably more, that I "heard" it, but wasn't finished with my "research", in "the world" at that time. My "research" being, or studying the "why", or the "how come", people, with God, and Jesus never leaving, nor forsaking, them would still want to knowingly WISH to continue in such a lifestyle! (great...the ruskies have reportedly just deployed a new "cruise" missile on a submarine...reportedly nuclear capable...hmm!)
This "research/rebellion(?)" led me into more drugs n alcohol, then ya can shake a stick at! Seems, in hindsight now, that I had merely been on a long leash! More importantly though, this leash had allowed me to become as rejected OF the world, cuz it couldn't break me, nor was I allowed, to conform to the world, and just as importantly, rejected by "churches of stone", cuz I couldn't be conformed by blind shepherds....I wanna help ya understands, what's occurred in my life, so, to aid others' who are experiencing similar circumstances, such as mine!.....Alone, and quite frustrated!.....A ROUGE!...No wife!...No children, No House (no house mortgage either...LOL)...No ties, to the world, Christian, family, or other ta wise!....Always asking myself WHY!....Wasn't til years later, and after having many times referred to myself as having the "Jonah Syndrome", that I took the proverbial bull by the horns, and was "learnt" about where my "place" in this "body of Christ" was by Gods' directive of "splitting the spoils", so to speak, of the "Promised Land"!
Hope this answers the question.
