WitnessingAfter some time of prayer, Bible reading, and fellowship, we moved to our regular spot in Queen Street Mall to begin our night of evangelism. Craig Ireland and a number of people from his Church joined us again for this outreach, which was a real blessing.

I stood up to preach first and talked about how every single human being knows there is a God (Romans 1). But what many people do is that they suppress this truth in unrighteousness. Alex (our weekly agnostic heckler) didn't like hearing this so he immediately began to heckle me with his usual line, "There is no God!" Since Romans 1:20 tells us that the way everyone knows there is a God is through "the things that have been made", I gave a simple argument for God's existence from the universe's existence. It is outlined below:

  1. Everything that has a beginning has a cause.
  2. The universe has a beginning.
  3. Therefore, the universe has a cause.

He said that there are examples in quantum mechanics (like virtual particles) of things that arise without a cause. However I responded by saying that wholly apart from the disputed question of whether virtual particles really exist at all, the central point to be made here is that the quantum mechanical vacuum on which they depend for their existence is emphatically not nothing. The dynamical properties of vacuous space arise out of its interaction with matter and radiation fields, in the absence of which "this dynamism of empty space is but a formal abstraction lacking physical reality." The quantum vacuum is a sea of fluctuating energy which gives rise to virtual particles. Thus, virtual particles can hardly be said to arise without a cause.

Alex simply ignored my point, and kept repeating that virtual particles are an example of something coming into being uncaused. So as to not get the discussion bogged down on this topic too much, I then talked about what is to come after we die. Since there is good evidence for God, the topic of the afterlife is very relevant to discuss. Alex brought forth his usual argument against any afterlife by saying, "Have you ever had a thought outside your brain?" Obviously we haven't. Therefore, he concluded that there is no afterlife. I pointed out that his conclusion does not logically follow from the argument's premises. For in order to prove a negative, one must either know absolutely everything about the subject matter to know it does not exist (like there are no Muslims in the U.S. Senate), or show a logical contradiction within it, making it impossible to exist (like a married bachelor). But Alex did not do either, so therefore his conclusion does not logically follow.

So I briefly outlined how we can know there is a judgment to come, and the existence of Heaven and Hell. I then proceeded to talk about how we've all sinned and fallen short of the glory of God. I warned both Alex and the crowd that had gathered that every idle word that you speak will be judged on the Day of Judgment. Jesus even said that lust is adultery. Alex did not like hearing about the judgment to come and sin, and so kept repeating, "There is no God!" After warning about the judgment to come, I gave the good news of the gospel to those listening. And that is, we can be forgiven of our sin through the death of the sinless Son of God, Jesus Christ. But we must repent and trust that He died on the cross for us. I also pointed out that we don't serve a dead Saviour, for three days later Jesus rose from the dead and is now seated at the right hand of God the Father.

God brought in quite a few people to hear the message he was preaching. After Andrew had finished preaching, he continued to chat with a couple of the people who had been listening for many minutes afterwards.

By the time Andrew got down there was only half an hour left to go on the outreach, and since we had no other spare preachers, we all instead focused our energies in handing out gospel tracts and witnessing one2one with people.

There were many people who heard the gospel this evening. Please pray that God will convict them of their sin and draw them onto Himself.
