Took me a while, but this is where I note down the come backs I would have/should have/have given when facing real life challenges, particularly in churches.
I was asked one time at Jireh Church (Marlboro township) by some member: You must have a lot of time from your job, that you can talk about/study theology?
Answer (should have been): Because America is a country full of Christian cults, we really should make time for theology! Making sure that we don't go to fake churches or for fake beliefs.
From a Crossroads Men's meeting (on challenging questions, i.e. can spy lie? etc.). When I took one of the given question list by the host and asked my group: So what do you think of this Israel challenges, do we support Israel, what is Israel to Christians? And I got the response from a black guy: It is a distraction from Christian love.
Answer (should have been): Ok, let me ask another question then, should Christian have debates? How would you sort out differences? Do we seek the truth or bury it?
To be continued with more examples...
