For if that which was fading away [i.e., the Old Agreement, represented by the law of Moses] had splendor, how much greater is the splendor of that which remains [i.e., the New Agreement represented by the Gospel]? [Note: In this section Paul uses the analogy of the fading splendor on Moses' face to the fading splendor of the Old Agreement].

For God, who said [Gen. 1:3], "Light will shine out of darkness," has [also] shone in our hearts to provide [us with] the light of the knowledge of God's splendor [as it shines] on the face of Christ. [Note: This allusion to "splendor shining on Christ's face" may be a continuation of the analogy used in 3:13].

And what harmony can Christ have with Belial? [Note: "Belial" means "worthlessness" and was used for referring to the devil]. Or, what does a believer have in common with an unbeliever?

But what I am doing, I will continue to do, so that I can cut off the opportunity from those who want an occasion [to receive financial support for themselves because of my example of receiving it]. They want to boast [that they are preaching] on the same terms as I do. [Note: Paul's argument seems to be that one reason for his foregoing financial support was so those "super apostles" in Corinth (see verse 5) would not be able to use his example to wrongfully exact financial support from the church].
