When witnessing do not allow yourself to get drawn into political debates; these are counter productive. As strongly as you may feel about a particular politician or issue, swallow your opinion. In an evangelistic context, you represent Jesus, not a political party.
Question: “What’s your view on the Iraq War?”
Good example: “It saddens me, really, as it is a perpetual reminder of the sinfulness of mankind. All war would be unnecessary if humans were definitionally good. God created the world as a perfect place where humans enjoyed an unbroken relationship with God and with his fellow-man. Sadly, there was a murder in the first family…”
Bad example: “George Bush was completely justified in…” or “I can’t believe we went in there like that; we had faulty intelligence…” Both are wrong answers in this context.
