The Law
I believe the law is very useful to convict the soul that he is a sinner. In Psalms 19:7 says "The law of the LORD is perfect, converting the soul: the testimony of the LORD is sure, making wise the simple." So I will give an illustration of how we can use the law of the Lord and convinced that the person is a sinner and is need of a savior. I am going to do a Role-play of what can happen if we get into a 1-on-1 conversation. John is a Christian and he is sitting next to a person named "Bob."
John: Hello there. I am John. What's your name?
Bob: Hello. I am Bob.
John: Nice to meet you Bob. Do you live around here?
Bob: Yes. I live 5 miles away from here. I live in New Holland.
John: Oh yes. It is a nice place. Did you live there for long?
Bob: Yes. I lived there for 15 years.
John: I see. So do you go to Church somewhere here?
Bob: Yes, I go to Church.
John: What is your Church's name?
Bob: Church of Christ. (I am throwing a random Church's name. I am not condemning any Church here.)
John: That's good. So do you think you are a good person.
Bob: Yes, John. I know I am a good person.
John: Really? Can I test you to see if you are a good person?
Bob: Certainly.
John: Well.... Bob. How many times have you told a lie?
Bob: A few times before.
John: What does that make you?
Bob: A liar.
John: Have you stolen anything?
Bob: No, I haven't.
John: Come on. You already admitted that you are a liar.
Bob: Well... When I was young, I stole a few small things.
John: What does that make you?
Bob: A stealer.
John: Be more specific.
Bob: A thief.
John: Have you hated anyone?
Bob: Yes, I have.
John: Bob, Jesus said that if we hate someone, we have committed murder in our hearts. So, have you looked at a girl with lust?
Bob: Yes, when I was younger.
John: Jesus said that if you look at a woman with lust, you have committed adultery in your heart. So right now, you are a liar, a thief, a murderer, and a adulterer. That is basically 4 of the 10 commandments you broke. If you stand before God on the judgment day and if He will judge you by the the 10 commandments, would you go to Heaven or Hell?
Bob: I would probably go to Hell.
John: Does that concern you?
Bob: Yes, it does.
I am guessing you know what to do from there. Now if you paid attention to the conversation, have you noticed on how he switched from the physical to the Spiritual just like that? So we can use the 10 commandments to convict the heart. And I think somewhere it says that the law shutteth every mouth.
Now let's go on a different route. I will break in the end of the conversation.
John: Jesus said that if you look at a woman with lust, you have committed adultery in your heart. So right now, you are a liar, a thief, a murderer, and a adulterer. That is basically 4 of the 10 commandments you broke. If you stand before God on the judgment day and if He will judge you by the the 10 commandments, would you go to Heaven or Hell?
Bob: I would probably go to Heaven.
John: Can you explain why you would go to Heaven?
Bob: Because God is understanding. He knows that I am just a person. I am not perfect.
John: That is true. We are not perfect. But just imagine this. If you committed murder and you were sentenced to life and prison. Would you say to the judge, "I know that you are a good judge. You would forgive me. You are understanding." The judge would say, "Yes, I am a good judge. But since I am a good judge, I will see that the crimes will be dealt with." You see Bob. We all sinned and offended God. But He sent His Son to die for us. Our debt has been paid. It is a gift from God, but we must believe it is our gift to have. It is written that the gift of eternal life is through Jesus Christ,our Lord."
Also, if you noticed something, you are asking questions. I believe that if you ask question, they would reveal where they're at with God or their knowledge of God. And never once did John judged him. Bob openly told John his faults and John used the 10 commandments to show him the sins he committed against God.
Also, did you notice something in the first RP? Bob said that he was a good person. That is pride. It is said in James that God will resisteth the proud and giveth grace to the humble. The law can and will take away that pride. And if you notice by the end, Bob actually humbled his heart to the Gospel.
Anyways, I will probably post part 2 later on about some questions we can use to reveal where they are at with the Lord or to lead into a conversation like John did to Bob.
Also, I think it would be a tremendous benefit if you watch Hell's Best Kept Secret. I watched it on youtube and it was a real blessing to me.
