{Through this man} (dia toutou). This very man whom the
Jews had crucified and whom God had raised from the dead.
Remission of sins (aphesis hamarti(936e)) is proclaimed
(kataggelletai) to you. This is the keynote of Paul's message
as it had been that of Peter at Pentecost ( 2:38  5:31  10:43 ).
Cf.  26:18 . This glorious message Paul now presses home in his
exhortation.
