Next time when you are defending Christianity, refrain from quoting from the Bible.
Do this so because the Bible is the Word of God to us. But to them it is rubbish.
(*Which* verse is this?)
So using Bible verses isn't *quite* necessary. You would just be *hitting blanks.
And I read somewhere that Paul wrote that the Bible would either strengthen your faith or harden your heart.
(Is this correct??*)
Wouldn't it, therefore, make matters even worse if we quote persistently and consistently from the Bible to non-believers.
Do we want to catch them or shoo them away?
Instead use your reasoning to defend Christianity. Be sure to be sound to the faith.
And if you really * need to use the Bible then use it.
*Perhaps you could quote wisely and eventfully. (As this is should be done debate-style)
Of course, there are times when you need to state a case from the Bible.
*deleted or changed accordingly
