Keil & Delitzsch

The Lord as ἀνακρίνων is, as in Co1 4:3., put in contrast with the ἀνακρίνειν of men, or of human ἡμέρᾳ. If men sit in judgment upon the righteous, yet God, the supreme Judge, does not condemn him, but acquits him (cf. on the contrary Psa 109:7). Si condemnamur a mundo, exclaimed Tertullian to his companions in persecution, absolvimur a Deo.
