Answer, Don't Answer Dr, Jason Lisle, a credentialed Astrophysicist, and apologetic lecturer, has derived an excellent answer to this apparent contradiction. Which turns out not to be a contradiction!
Answer not a fool according to his folly... (Proverbs 26:4)
That is, don't try to answer a critic (of Christianity) accepting his premises...his statements...his presumptions. If you get sucked into accepting them uncritically you will be trapped into following him down his path to his conclusions. Once you say you believe his foundational beliefs, you are obligated to accept their deductions/implications. You will belike unto him. You will be as erroneous as he is.
So never accept an invitation to debate based on his premises; that is, with his stipulations. Obviously, the secular atheist has a whole set of premises that are contradictory to the theistic worldview. They are incompatible, and one must not give in to accepting any of them...and hope to come to a legitimate conclusion (debate victory).
Answer a fool according to his folly...(Proverbs 26:5)
If, however, a secularist persists on debating only with his premises, then force him to take his argument down to its logical conclusion. Since his premises are faulty (unsubstantiated, illogical, or fallacious), then when taken to their logical conclusion, they will be seen to be absurd! Force the fool to continue on down the path until he self-destructs! Until his position loses its credibility...in the real world of reason and logic!
He then can not consider himself wise in his own estimation ("conceit", KJV)! He will recognize his foolishness. He is trapped by his own premises. Q.E.D.
