Romans 8:33

‘Who will lay anything to the charge of God's elect? It is God who justifies.'

In Romans 8:32 Paul's language was sacrificial, now it becomes legal. What possible charge can be laid against God's true people, those ‘chosen' as described in the process in 29-30, and who would dare to lay such a charge, when God Himself has accounted them as righteous (justified them) on a totally satisfactory judicial basis, as described in Romans 3:24 to Romans 4:25.

An interesting contrast can be made here with the one who brought a charge against Israel's High Priest in Zechariah 3. There God answered it by replacing his filthy garments with clean ones so that the charge failed. But here Paul is referring to those who have already been cleansed. They have already received their ‘robe of righteousness'. In their case therefore any charge would be futile.
