“Therefore, since we have been made right in God’s sight by faith, we have peace^[a] with God because of what Jesus Christ our Lord has done for us.” Romans 5:1NLT My long ago memorized KJV version says “Therefore being justified by faith we have peace with God through our Lord Jesus Christ.. 

Footsteps #287 Please read Romans 5.  If I were to liken the first 5 chapters of the book of Romans to a four-part symphony, the Sonata would be the opening chapter where the theme is introduced and the various players are heard from. The strong theme or melody of the entire symphony of course is justification by faith. The first chapter (movement) is brisk and lively, the second and part of the third chapter is slower and more lyrical. From chapter 3:19 to 4:24 we have the boisterous minuet and then Chapter 5 would be the rollicking finale. Paul has been following a pattern. Paul’s symphony is the most profound, most stirring, and most significant piece of work of his entire career if not that of the entire Christian authorship community. Notice the triumphant beginning to Romans 5:1 “Therefore!” This is the certainty of complete and final salvation that brings us ‘peace with God.’  Pursuing peace is a universal human quest whether that be in the realm of personal, international, domestic, or spiritual peace. Everyone is interested in peace. But beyond peace, in general, is peace with God. Paul alluded in Rom.1&2 to a universal sense of guilt. Cultures and languages may differ, but the underlying needs of peace of mind and peace with God transcend them all. 

Rom.5:1 is Paul’s answer to that universal human quest. He is connecting it to his presentation on justification by faith in Rom.3&4 by the word “therefore”. First is the sense of assurance of salvation possessed by those who have accepted Christ by faith. We can have peace because we know that we are right with God. Such assured peace does not rest on our subjective feelings, but, as Paul argues in chapters 3 and 4, on the objective reality of Christ’s finished work on the cross and His resurrection from the dead (Rom.4:25). 

A second sense in which we have peace is that of the fruit of the Spirit, which Paul describes in Galatians 5. Thus some of the results of justification are joy and peace. The Christian believer knows that real peace comes only from being in a right relationship to God.
