For a more careful execution of this topic refer to my Romans series at The Bible Archive. My main point will be this: that the Gospel winds up being a practical help that can be used to cure any form of boasting evidenced in cynicism, pharisaicism and judgmentalism. To prove this, I’ll focus on Paul’s argumentation in Romans.
This measure of our object of faith finds its power in the fact of the gospel. Christ became a servant in that Gospel so now, as a new humanity with new life, we can be proper God honoring servants. On behalf of God’s truth, Christ become a servant to those of the circumcision to authenticate and make real all of the promises given to the Jewish forefathers so therefore a Gentile believer can be a servant to those of the circumcision on behalf of God’s truth as well. Here’s how.
The Measure of Faith comes to work in this concept of the “weaker in faith” and the “stronger in faith”. Now here I’ll have to do some preliminary defense of my previous (and continued) position on the measure of faith. For in the sense that some people take it (this person has more God-give-faith-power and this person has less God-given-faith-power thus I have more God-given-faith-power then X or less then Y) it starts bolstering ourselves in an area that Paul says to think soberly about. But the fact is we really don’t know the faith in another person: that’s an impossibility. All we know is the actions of another person.
This Measure of Faith also becomes useful in dealing with the enemies (be they Christian or Non) of a believer. For when a person understands that they were a God Hating Idolater for whom Christ died and God justified and promised to glorify then a believer can become an advertisement of mercy for anyone.
That measure of faith is inherently pointing at the object which the believers have put their faith and thus performs a complete leveling influence to Christian living. Note how aptly Paul draws the Measure of Faith in the area of the Church Body.
