Aside from noting that…
- There is evidence that God exists.
- There is evidence that Jesus Christ is the unique God-Man.
…one can also specifically address this ludicrous claim:
Take the most outrageous claim of Christian doctrine: That the eternal, omnipotent Lord and Creator of the universe became a Jewish baby. Did it take “thousands of years” for this to become believable?
No, it didn’t.
In point of fact, it was believed decades before the end of the first century A.D. by an increasingly large number of people, many (if not most) of whom were Jews themselves, the people in the Roman Empire least likely to believe the Incarnation could be true. In just less than four centuries (hardly “thousands of years”), Christianity was not only believed throughout the Roman Empire, but had become the dominant and official religion of the Empire.
