Romanos 5:9

So far Paul had referred to five benefits of justification. These blessings, in addition to justification itself, were peace with God (Romans 5:1), access into a gracious realm (Romans 5:2), joy in tribulations (Romans 5:3-5 a), and the indwelling Holy Spirit (Romans 5:5 b). Still there is "much more" (cf. Romans 5:10; Romans 5:15; Romans 5:17; Romans 5:20).

What Paul next described is a benefit that justified sinners will experience in the future, namely, deliverance from the outpouring of God’s wrath on the unrighteous (cf. Romans 1:18). Jesus Christ’s blood is the symbol of His death and the literal expression of His life poured out as a sacrifice (cf. Romans 3:25). Having done the harder thing, namely, justifying us when we were yet sinners (Romans 5:8), how much more will He do the easier thing, delivering us from coming wrath.
