The Justice of God: He is Just and He Justifies

Deuteronomy 32:4

4   “The Rock, his work is perfect,
    for all his ways are justice.
  A God of faithfulness and without iniquity,
    just and upright is he.

(ESV)

Romans 3:25–26

25 whom God put forward as a propitiation by his blood, to be received by faith. This was to show God’s righteousness, because in his divine forbearance he had passed over former sins. 26 It was to show his righteousness at the present time, so that he might be just and the justifier of the one who has faith in Jesus.
