Romans 8:33

The question that opens this verse, along with the two others that follow in Romans 8:34-35, brings out the implications of "If God is for us, who is against us?" (Romans 8:31).

Satan is the accuser of the brethren (Revelation 12:10; cf. Job 1-2). He charges the elect with sin. However, when he does this he gets nowhere with God because all sin is against God ultimately (Psalms 51:4). Therefore God is the only one in the position to charge the believer with guilt. He will not do so because He is for us. He has provided His Son to pay the penalty for our sins, Christ has done that, and God has already declared us righteous.
