As well, you should listen to a sermon by Gary Webb on guns (available here), the second amendment and the responsibility of Christians.
During brief moments that I'm not obsessing over what other people are doing wrong and not writing on this blog, I memorize one verse a week. I lead our whole church in memorizing the same verse. Actually, if I multitask, I can both obsess and perform other tasks at the same time. I recently have been singing in our choir, and I'll often work on Bible memory then too, so I obsess plus sing plus memorize. It's tough, but you've got to do whatever you can to maintain your obsessions. We are memorizing a chunk of Philippians 3 right now, and this last week we memorized v. 9, which reads:
And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:
Notice that saving righteousness, justification, comes "through the faith of Christ." "Faith of Christ," not "faith in Christ." "Of," not "in." That should stick out to anyone, because "of Christ" reads a little odd to us, because it is obviously making a point. In the Greek text, "faith of Christ" is two Greek words and "Christ" is in the genitive case, hence, "faith of Christ." "Christ" is not in the locative case, which would translate, "in Christ." It is genitive, "of Christ."
When you have a genitive case as such, you do have to make a decision on what the genitive is saying. There are different types of genitives. By the way, it is actually tough to think about the use of the genitive and obsess over what other people are doing wrong, but it is a finely tuned craft with me, so both can occur simultaneously with regular practice. (I happen also to be eating French toast right now for those interested in my status. I'm wearing sweats and a stocking cap and the thought of mouthwash occurred to me while still obsessing, of course). Is it a genitive of description, an attributive genitive, genitive of apposition, an objective genitive, a subjective genitive, a partitive genitive, a possessive genitive, or some other genitive?
Some non-Calvinists out there are so anti-Calvinistic that they are against faith not being a work. They fight against what they see as a Calvinistic idea that faith is not a work. It is part of the anti-Calvinistic scorched earth defense against Calvinism, and a definite failing defense. My anti-Calvinist friend, please stop this obsession, and not to point out your error, which is my obsession, but faith is not a work. If faith were a work, then salvation would be by works. But even without that bit of logic, Scripture teaches that faith is not a work. Now back to the genitive in Philippians 3:9.
"Of Christ" is not a genitive of description, because it is not a Christ type of faith or kind of faith. An example of a genitive of description is the phrase, "day of salvation.' This isn't that. It is not attributive, because it is not saying that Christ is faithful, such as "man of peace," which could be restated, "peaceful man." It is not a genitive apposition, because faith is not Christ, that is, Christ is not a restatement of faith. It is not a subjective genitive, because it is not the faith that Christ Himself is practicing. It is not an objective genitive, because that idea would normally be expressed by "believing Christ," that is, seeing Christ as the object of the faith. It is not a partitive genitive, because it is not faith that is a part of Christ. It is not a possessive genitive, because it is not strictly Christ's, because it is also yours. So what genitive is it? It is simply a genitive of source. Jesus is the source of saving faith. The faith of Christ, the faith that comes from Christ, is the faith through which we receive the righteousness of God.
What will make this easier is to parallel, which you should, "of the law" with "of Christ." Paul's own righteousness was "of the law," that is the source of it was his own lawkeeping. Expositor's Greek Testament says that it is the faith which Christ "kindles, of which He is the author, which, also, He nourishes and maintains." This is like Galatians 2:20, where Paul writes, "I live by the faith of the Son of God." It isn't faith "in the Son of God," but faith "of the Son of God." It is genitive. Galatians 3:26 translates "faith in Christ" and it uses the preposition en, "in." When you want "faith in Christ," you can use the locative case and the Greek preposition en (same in Colossians 1:4, 2:5 uses eis for "faith in Christ" as does Acts 24:24).
Faith is a gift, not a work. This is also backed up by Philippians 1:29. Read that verse. Anti-calvinists, you don't help your case by arguing against faith as a gift. You come across as people who are willing to twist Scripture to fit your predisposition. Faith is not a work. We are saved by faith, which is not a work. Faith itself is not a work and is not of works. Salvation is by grace alone.
