Not sure why I should believe you - you have no choice whether or not you believe it's true, even if it isn't. Right?
You shouldn't believe me. You should search the scriptures to find out if these things are so. If one honestly read the scriptures through a Reformed perspective (the outward and inward calling of man), then it is difficult to reject what is being said. The scriptures are not complicated in the Reformed light (well-perhaps Revelation).
I would suggest an honest reading of the Gospel of John. If people would simply take the time and read this entire gospel through the outward and inward call of man perspective, they could come to no other conclusion then God chooses men.
