JMNT(i)
30 For just as you folks were once (or: at one time)
incompliant to God (or: unconvinced, disobedient, unwilling to be persuaded and stubborn by God),
yet now (at the present time)
you folks are (or: were)
mercied (made the recipients of mercy)
by (or: in; with)
the incompliance (disobedience; stubbornness; lack of being convinced)
of these folks.
31 Thus, also, these now (at the present time)
are incompliant (stubborn; disobedient; unconvinced)
by (or: for; to)
your mercy, to the end that they also may now be mercied (would be the recipients of mercy).
32 For you see, God encloses, shuts up and locks all mankind (everyone; the entire lot of folks)
into incompliance (disobedience; stubbornness; lack of being convinced),
to the end that He could (or: would; should)
mercy all mankind (may make everyone, the all, recipients of mercy)!
