“A good many people think of justification as the first or initial blessing of the Christian life, it’s value ending at that point… Justification is not only the first or initial blessing, but justification carries with it every other blessing of the Christian life, and when a man is justified, he has everything that God has to give." 
McClain lists twelve blessings of justification.
1. Being justified by faith, "we have peace with God."
2. Being justified by faith, "we have access, by faith, into this grace."
3. Being justified by faith, we have a standing in grace.
4. Being justified by faith, we have joy ("we rejoice") "in hope of the glory of God."
5. Being justified by faith, "we glory in tribulations." Glory is the same word in the Greek as "rejoice". Being justified by faith, we "rejoice ... in tribulations." We have joy in our tribulations. The unsaved man cannot rejoice in his tribulations.
6. Being justified by faith, we have a hope that "maketh not ashamed."
7. Being justified by faith, we have "the love of God ... shed abroad in our hearts." We have an experience of the love of God.
8. Being justified by faith, we have the Holy Spirit. A justified man need not anxiously look for a future time when he will receive the Holy Spirit (but he can be filled and filled again, and he can grieve the Holy Spirit, andhinder his faith walk). This fifth verse is a remarkable verse, for it is the first occurrence in the Book of Romans of the Holy Spirit, and here too the love of God is first mentioned.
9. Being justified by faith, we have the proof of God' love because "Christ died for us."
10. Being justified by faith, we are going to be "saved from wrath." We have immunity from wrath to come.
11. Being justified by faith, we are going to "be saved by his life." This is no denial of the fact that we have already been saved, but this is looking forward to something else.
12. Being justified by faith, we "rejoice in God." We are not afraid of Him any longer, but we actually rejoice in God. We look at Him, see Him in all His holiness, and we rejoice in Him!
