Robertson's Word Pictures (NT)
Because (dioti). Gives the reason (dia, oti like our "for that") for the revelation of God's wrath.
That which may be known of God (to gnwston tou qeou). Verbal adjective from ginwskw, either "the known" as elsewhere in N.T. (Acts 1:19; Acts 15:18, etc.) or "the knowable" as usual in ancient Greek, that is "the knowledge" (h gnwsiv) of God. See Philippians 3:8. Cf. same use of the verbal xrhston in Romans 2:4, ametaqeton in Hebrews 6:17.
Manifest in them (faneron en autoiv). In their hearts and consciences.
God manifested (o qeov efanerwsen). First aorist active indicative of fanerow. Not mere tautology. See Romans 2:14-16.
