I am not sure it is right to call people Moody's "followers". In fact, I am fairly certain that he would object, if he were living.
I believe that Moody was one of the greatest evangelists of his day, early on this was probably the result of his philosophy of combining evangelism with effective social work. He was involved in the daily life of his community, was president of the Chicago YMCA for a few years, and while he refused to fight he worked with the United States Christian Commission to evangelize the Union troops. His evangelism saw more fruit when he decided to integrate music in his evangelistic campaigns and toured with Ira Sankey (“The Sweet Singer of Methodism”).
Moody developed many of the methods we saw in later “crusades”, to include a house to house canvass before a crusade, seeking interdenominational cooperation from local churches and lay leaders, renting large buildings in the towns, using an inquiry room for those wanting to repent, seeking the support of the business community, and showcasing gospel soloists.
And, of course, he began training people to reach others. In 1879 he started Northfield Seminary for girls, and in 1881 Mount Hermon School for boys. This goal to train people for the Kingdom work resulted in what would become the Chicago Evangelization Society, later renamed the Moody Bible Institute.
And I think that we can also use tracts that express the gospel well in our witnessing to other people. It is not that passing out tracts is evangelism, but I see no reason to avoid tracts either.
Do not take this wrongly.
You may think it legal, but you show a fundamental lack of respect for others' property rights when you leave trash (that is essentially what it is, since it either ends in the garbage or as litter) on vehicles not your own.
I think that it is a poor witness.
Not against tracks in and of themselves. Moody's day was not today. Back before everyone had air conditioning people sat on their porches in the evening and people talked with neighbors. Now we shut ourselves in, close the doors and close the curtains and get offended if someone stops by unannounced. The culture has changed. In the same way tracks are seen as just another advertisement that people do not want to be bothered with.
Tracks can be used as a supplement to a short conversation we have had with someone. Handing them out in shotgun fashion like birdshot should never be a primary means of sharing the gospel. Take your time, allow for the leading of the Spirit, be prayerful and you will always speak with authority. Otherwise you are like the grading noise of fingernails on a chalk board.
Anytime someone goes out and preaches the gospel they should do it with sincerity and in the Spirit I pray at least one person is saved. I pray that for you as well. Be careful, be wise, be filled with the Spirit, and do your level best to walk in holiness. Most important be concerned about the people who you are giving a track or preaching on the corner to. Be concerned that they get saved, be concerned that they will then walk with the Lord, be so concerned about these things that you would gladly give your life up if they would come to Christ. When they don't it should break your heart.
You have used Comforts videos. Did you know that he sells tracts? The million dollar bill for example is meant to be handed out to everyone. He makes other tracts that are more designed for deeper conversations, and also booklets. Tracts are not all the same and can be handed out shotgun style as you mention, and others are more meant for deeper conversations.
I get so annoyed when people put things on my car and because I'm a good citizen who hates to litter, I now have to carry that garbage around in my car until I get to a pail where I can throw it out.
I have called businesses and told them that specifically because they put something on my windshield, I will never pay them a visit.
I know most people feel the same way.
If I'm walking in public and someone is handing out ANYTHING I will not take it. It could be actual, real dollar bills and I wouldn't take it. This mostly happens in downtown Minneapolis when leaving sporting events or movie theaters. A lot of times I'll stop walking, look at the person in the face, look at their hand holding their literature, then walk away.
