Preaching DOES require exposition and exhortation; and none of that will happen within a couple hours(except maybe on a weekend or holiday) without Uncle Dan's Silver Hammer coming down on one's head!
Perception is 9/10's of the reality that most people walk in, if the question begins with, "What was Jesus's answer to the woman at the well..." we would instantly assume it's Protestant; if the question says, "Where in the Tanach does it say..." we would assume it addresses a Jewish audience; if the question says, "What is the ethos of the author...." we would assume "post modernist/higher criticism...."
IF=One Takes Scripture(The Text) Seriously; THEN=One Must Be Open To What The Text Says,
This is not preaching! However, when one goes beyond WHAT the Text says, and takes it upon themselves to p_r_o_s_c_r_i_b_e what someone should do with it, then we have "Crossed A Line" which we may have God's Blessing and favor upon, but not Uncle Dan's!
(Hint:All You Evangelical's-You Can PRAY for Your Audience-Really!) If you exposit the truth, then it Will set people free. And I see nothing in the site guidelines that forbid us to pray for individuals. Otherwise, "Proscribing what someone might do with the answer you gave is beyond the scope of this site, and may get you time in the Penalty Box if you persistantly refuse to heed counsel".
Just a personal note...I am all for evangelism, street witnessing, power encounters, going up to total strangers and asking"...if you died today, where would you go?" "I am not ashamed of the Gospel, for it is the power of God unto Salvation for all who believe.."(Rom. 1:16) But there are 'overt' and 'covert' ways, and those that laid out the guidelines to this site believed that 'questions from and about the text' make for the widest audience participation, and allow those to ask questions and receive answers in a non-partisan environment.
