How to put your theological education to good use

"A good rule of thumb is that if you cannot express your ideas in ordinary language that the person in the pew could understand, then they are probably not worth airing. If you need to talk about 'realized eschatology' and 'redaction critical technique' then either you haven't grasped the ideas very firmly yourself or they are probably pretty irrelevant."
