For these things (pros tauta). From Rom 8:12 on Paul has made a triumphant presentation of the reasons for the certainty of final sanctification of the sons of God. He has reached the climax with glorification (edoxasen in Rom 8:30). But Paul lets the objector have his say as he usually does so that in Rom 8:31-39 he considers the objections.
If God is for us, who is against us? (ei ho theos huper hēmōn, tis kath' hēmōṅ). This condition of the first class carries Paul’s challenge to all doubters. There is no one on a par with God. Note the two prepositions in contrast (huper, over, kata, down or against).
