Prayer request

I attended a conference yesterday and the Lord gave me some ideas or re-inforced previous ideas I had forgotten. The conference had a heavy emphasis on evangelism and so I am writing random snail mail letters and including gospel tracts to various false churches and even some Jewish Synagogues/temples in my area. I have located a Word of Faith Church, seeker churches, an emerging church, and perhaps the most terrible a church that has no problem at all with homosexuality, and openly allows gays & lesbians to participate. Pray that my letters will be written in gentleness and respect (1 Pt 3:15) but also serve as a warning to the lost for whom else would warn them of their ways leading to eternal destruction? Pray for impact. Thanks..
