In Romans 1–11, Paul showed the mercy of God toward us sinners. Then, knowing of God’s mercies toward us, Paul wrote in Romans 12.1–15.6 that we live a certain way, and in Romans 15.7, he showed a glorious way to live out what God has done toward us, 

“Therefore receive one another, just as Christ also received us, to the glory of God” (Romans 15:7). 

Has Jesus received you? Then receive others whom He has received, which will all be toward the glory of God.
