Some translations set each line of poetry farther to the right than the rest of the text to make it easier to read. The ULB does this with verse 20 of this chapter, which are words from the Old Testament.
Many scholars believe Paul uses the word "therefore" in [Romans 12:1](./01.md) to refer back to all of Chapters 1-11. Having carefully explained the Christian gospel, Paul now explains how Christians should live in light of these great truths. Chapters 12-16 focus on living out one's Christian faith. Paul uses many different commands in these chapters to give these practical instructions. (See: [[rc://en/tw/dict/bible/kt/faith]])
Under the law of Moses, people were required to offer temple sacrifices of animals or grain. Now Christians are required to live their lives as a type of sacrifice to God. Physical sacrifices are no longer required. (See: [[rc://en/tw/dict/bible/kt/lawofmoses]])
The body of Christ is an important metaphor or image used in Scripture to refer to the church. Each church member plays a unique and important function. Christians need each other. (See: [[rc://en/tw/dict/bible/kt/body]] and [[rc://en/ta/man/translate/figs-metaphor]])
