Lewis,Within a few weeks of when I trusted in Jesus as my Saviour, one of my coworkers started riding along with me in my car.At that time, I was working at a laboratory out near O'Hare airport, and then traveling to the south side of Chicago to go to evening classes.The coworker lived on the near north side of Chicago, and asked to catch rides home with me, as I drove into the city each evening.He offered to pay, but I refused, so, instead, he bought me a book, Alexander Hislop's Two Babylons.When I was saved, I was still in the catholic church, and I quickly began noticing how many catholic doctrines and traditions were different than the Bible.But then Hislop's book began to totally blew my mind, and I soon became vehemently anti-catholic, even trying to debate catholic priests.When I was first saved, I initially tried witnessing to fellow catholics, so that they, too, could be saved.But, later, the more I studied Hislop's book, the more I only told catholics about the things wrong with the catholic church.If you are familiar with the tracts by Jack Chick, there are two extremes, shown by a couple of his tracts.One, The Greatest Story Ever Told, is one that can easily be used to witness the gospel with.The other, The Death Cookie, is not as practical a witnessing tool, as it is more extreme in regard to the catholic doctrine of transubstantiation.I had become more concerned with disproving catholic false doctrine, than I was in witnessing the gospel to catholics.I was in the process of making my own tract, when I was convicted that I was going about things differently than I originally did after I was first saved.So, I got rid of Hislop's book, and went back to evangelism.It turns out that witnessing at Christmas is really an effective time, as most people won't get angry about talking about Jesus at Christmas.In addition to one-on-one witnessing, and door-to-door, there was also open air.So, there was still preaching, singing, and witnessing in front of Holy Name Cathedral while people lined up for midnight mass Christmas Eve.Many would ask why we were talking and singing about Easter at Christmas.Which was a great open door to connect Jesus coming into the world so that he would go to the cross to die for our sins.Similarly witnessing, tract passing, and preaching at the Hillside Cross, where many catholics would come thinking that the queen of heaven had appeared there.Many catholics got the gospel, and a number believed on Jesus, but that was after no longer using Hislop's approach.
