Well said!
The fact is, few actually "know", and most only "believe." But there are those who have and do "know" what is true, and these have and do testify to the truth--while millions upon millions only speculate resulting in much conjecture. Nonetheless, there exists a thread of evidence by eyewitness testimony about what can be "known" of God and the truth. It is this thread of actual truth that has been presented down throughout all the ages that establishes the 'belief' of many, and it is in this undeniable history of events and testimony that many place their hope.
But this hope and belief is not by logic or an ability who's source is their own--it is a gift, as it is written, a gift "
like treasure hidden in a field, which a man found and hid; and for joy over it he goes and sells all that he has and buys that field."
Matthew 13:44 Which is the judgement of God to know who is of Him, and who is not.
