Romans is a deep theological treatise (It took D. Martyn Lloyd-Jones 12 years to preach through the letter!). Notice some of the words Paul has used so far ; Justification, propitiation, reconciliation, sanctification, adoption, redemption, glorification, election. You can (and should!) spend extended time studying and meditating on God’s glorious grace in these truths.
But let’s back away and take a ‘big picture’ look of how this great salvation, justification by grace through faith alone in Christ alone, affects Paul’s life and ours. After expounding the deep theological truth of the gospel, Paul shifts immediately to mission:
First, Paul shows his heart for mission as he grieves the lost souls of the Israelites-
[9:1] I am speaking the truth in Christ—I am not lying; my conscience bears me witness in the Holy Spirit— that I have great sorrow and unceasing anguish in my heart.  For I could wish that I myself were accursed and cut off from Christ for the sake of my brothers, my kinsmen according to the flesh. (Romans 9:1-3 ESV)
Paul then shows how this gospel gets out:
 For “everyone who calls on the name of the Lord will be saved.” How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching?  And how are they to preach unless they are sent? As it is written, “How beautiful are the feet of those who preach the good news!”  But they have not all obeyed the gospel. For Isaiah says, “Lord, who has believed what he has heard from us?”  So faith comes from hearing, and hearing through the word of Christ.(Romans 10:13-17 ESV)
Meditate on the greatness of God in the gospel. first, let it bring you to your knees in humble adoration. second, let it break your heart that there are those around you who do not trust in Christ for salvation. Lastly, go with the gospel!!!!!
