Looks like the guy is trying to teach the fallacious thought that we can 'reason' people into believing because the 'bible makes sense' or some such absurdity.
Faith in something we CANNOT actually SEE with our eyes goes beyond a book and the letters on pages therein.
Jesus said "NO MAN comes to me unless the Father draw him"...ie there is no amount of reason and logic or trying to make the bible and christianity 'sound' acceptable that will cause a man to believe it.
If the Father is not drawing a man CANNOT come...or Christ be a liar.
If the Father IS drawing then the truth will go into this persons heart and if they are open to Him then they WILL come to Him in repentance and it wont matter if the person bringing the gospel says "because the bible says so"....the person being saved WILL believe if his heart is readied.
MUCH of the reason that so many fall away from the faith is frankly because they were NEVER actually in the faith.
They were 'reasoned' into following something they didnt really understand because the Father had not laid the groundwork in their hearts or someone tried to 'reason' them into buying a religion.
I'll stick with my "bible says so" and let the Father do the rest.
That way when a person DOES come to Christ it is genuine....not just because I sold them a new religion.
