A bit of clarification:
Yes, God is in control and is allowing these things to come to pass.
Why is He allowing these things to come to pass? :idunno
(some may have thought I was asking 'why is He not in control)
I tend to agree. Bringing someone to the Lord through apologetics is similar to 'bringing spmeone to the Lord', through getting them to recite the sinner's prayer. It must be the Lord's work with or without the aide of such maneuvers.
