And I want you to be aware, brothers, of how frequently I [had] planned to visit you (but was prevented from doing so until now). I wanted to come in order to bear some fruit [i.e., make additional converts] among you, just as I have done among the other Gentiles [i.e., unconverted people].
God presented Jesus as the atoning sacrifice [i.e., a “covering over” or forgiveness of our sins] through [our] faith in His blood [i.e., His death on the cross]. This was in order to demonstrate His justice when, by using forbearance, He passed over people’s sins in previous generations.
But the Scriptures indicate that everything [i.e., everyone] is under the control of sin, so that the promise [of never ending life] could be available [only] to those who have faith in Jesus Christ.
And on one hand, many people were appointed to be [Levitical] priests because they were prevented by death from continuing [to serve]. [Note: The idea is that Levitical priests had to be constantly replaced].
