Tactics

As a christian apologist you will need some tactics and you will need to learn how to catch contradictions

examples:

"We don't have any knowledge about metaphysics"

"then how do you know that about metaphysics?if we can't know anything about metaphyisics how do you know we can't know anything about metaphysics?we can only know that if we can know something about metaphyisics"

"The purpose of life is to rid yourself of all desires"

do you desire to rid yourself of all desires?

"There is no Truth"

Is that true?

''You can't know the truth''

Than how do you know that about truth?

also,in situations like in the last example you would probably want to ask ''what do you mean by truth?",because maybe by ''truth'' he means the true religion,the true worldview.

more examples:

''There is no God"

What made you come to that conclusion?

Have you ever considered_?(fill the blank with some evidence or argument(s))

"True for you but not for me"

is that true for everybody?

yeah,try that with your teacher though

"oh come on,i learned a lot and i deserve an A"

"but you couldn't even mumble a single word"

"Hey,that's true for you but not true for me,come on,just give me that A!"

''All truth is subjective"

is that a subjective truth?

"truth is only found in science"

is that a scientific truth?is it scientifically true that truth is found only in science?

"every religion is the same"

What made you come to that conclusion?

have you ever considered_?

''Love is my religion"

what do you mean by ''Love"?what do you mean by "religion"?

What made you come to that conclusion?

have you ever considered_?

You get the point.

Also,an advice which i as a christian apologist would like to give literally to everyone including atheists,christians etc... is:

Don't be arrogant,it makes you look like a jerk and if you are very arrogant while being wrong well...i just feel like that's not good,i feel like that's embarrassing,well...not only that i feel that but i experienced it,and arrogance can defeat you a lot of the times in your debates/discussions.
