You know, I agree with all of this, with this caveat: you are using several different terms for several different kinds of law: OT law, their own laws, the twisted law of the yakuza, men's law. My question is, which law is necessary for evangelism, as per the OP? My immediate reaction to the OP was that it was talking about OT law, in which case I disagree that it is needed for evangelism.True, some do.
First, you know as well as I do that no man can convince another of being a sinner as this is the work of the Holy Spirit. But scripture tells us that where the OT law is absent, their own law is the testimony against them. Therefore the man you spoke with already understood in a basic way, sin - based upon their own laws. You having brought it to him from a biblical perspective was God's way of bringing him to full truth of what is sin and righteousness. As I stated this concept was something he only grasped because of the shadowy figure of men’s laws which stood against him.
But even you can't get around the law in your witnessing because as you stated "a pure heart is needed to enter a pure heaven, and only Christ can do that". Your entire point is based upon the Law, of which, is there to show us what is sin and perfection. Even the yakuza have laws, and based even upon their own twisted version they can grasp the concept of right and wrong using their laws to 'illustrate' the biblical concepts (such as breaking them and punishment for it).
No man can be saved until he knows he is lost and this can only come about if he know 'why' he is lost. If he knows why, then the gospel message will become evident to him as to why Christ not only is The Savior but 'why' he is the Only Savior.
I agree that it is only the Holy Spirit who brings conviction of sin.
Yet the law is used, whether OT or mans, to prove not only 'what' sin is but 'that' it is. As I said with respect to Paul’s argument, he would not know what sin was if it had not been for the law. And it is because he now knows what sin is that he knows he needed a saviour. This is whole crux of the gospel message. But I am sure you arleady know this so I will step out now.
The Greek word nomoV has a very broad range of meaning, much like the English word law. It can mean anything from civil law to OT law to "principle." My BAGD lexicon has almost three whole columns on it. However, some languages (Japanese for example) distinguish the meanings with separate words.
I propose the following:
1. OT law: not needed for evangelism, but useful.
2. Civil law: not needed for evangelism, but useful.
3. Subculture law (yakuza for example): not needed for evangelism, but useful.
4. The law of conscience (God's law written in the heart, but corrupt): not needed for evangelism, but useful.
4. God's law, much stricter than even OT law as evidenced by the Sermon on the Mount: absolutely necessary for evangelism.
We're praising the Lord! Japan is tough sledding, which makes the victories that much sweeter.BTW - It sounds like God is working over there and in your ministry. That is GREAT brother, exciting!![]()
