For the Son of God, Jesus Christ, who was preached among you by us, by me, Silvanus, and Timothy, was not “Yes” and “No,” but has proved to be “Yes” in Him [true and faithful, the divine “Yes” affirming God’s promises].

So we look not at the things which are seen, but at the things which are unseen; for the things which are visible are temporal [just brief and fleeting], but the things which are invisible are everlasting and imperishable. Cross references: 2 Corinthians 4:6 : Gen 1:3 2 Corinthians 4:13 : Ps 116:10 end of crossrefs

He made Christ who knew no sin to [judicially] be sin on our behalf, so that in Him we would become the righteousness of God [that is, we would be made acceptable to Him and placed in a right relationship with Him by His gracious lovingkindness].

For [you can look back and] see what an earnestness and authentic concern this godly sorrow has produced in you: what vindication of yourselves [against charges that you tolerate sin], what indignation [at sin], what fear [of offending God], what longing [for righteousness and justice], what passion [to do what is right], what readiness to punish [those who sin and those who tolerate sin]! At every point you have proved yourselves to be innocent in the matter.

so that we may preach the gospel even in the lands beyond you, but not to boast in work already accomplished in another one’s field of activity.
