if only I may finish the race and complete the ministry that I received from the Lord Jesus

This speaks about Paul's "race" and "ministry" as if they are objects that Jesus gives and Paul receives. Here "race" and "ministry" mean basically the same thing. Paul repeats this for emphasis. Alternate translation: "so that I may complete the work that the Lord Jesus has commanded me to do" (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-doublet)
