17 In Christ Jesus, then, I have legitimate reason to glory (exult) in my work for God [in what through Christ Jesus I have accomplished concerning the things of God].
18 For [of course] I will not venture (presume) to speak thus of any work except what Christ has actually done through me [as an instrument in His hands] to win obedience from the Gentiles, by word and deed,
19 [Even as my preaching has been accompanied] with the power of signs and wonders, [and all of it] by the power of the Holy Spirit. [The result is] that starting from Jerusalem and as far round as Illyricum, I have fully preached the Gospel [faithfully executing, accomplishing, carrying out to the full the good news] of Christ (the Messiah) in its entirety.
20 Thus my ambition has been to preach the Gospel, not where Christ’s name has already been known, lest I build on another man’s foundation;
21 But [instead I would act on the principle] as it is written, They shall see who have never been told of Him, and they shall understand who have never heard [of Him].
