What does 1 Timothy 6:12 mean?
Verse 11 commanded Timothy to flee from sin and temptation, and gave a list of positive character traits to pursue, instead. In this verse, Paul provides two imperatives. First, Timothy is to, "Fight the good fight of the faith." This wording closely resembles words Paul will use regarding himself in his second letter to Timothy (2 Timothy 4:7). The metaphor of our spiritual warfare as a boxing match is not unusual for Paul, who also spoke of the Christian faith as a boxing match or fight in 1 Corinthians 9:26: "… I do not box as one beating the air," referencing the idea of shadow boxing.Paul's second command in this verse is for Timothy to live as if he has eternal life already. Paul mentioned eternal life earlier in 1 Timothy 1:16 and often spoke of it in his letters (Romans 2:7; 5:21; 6:22, 23; Galatians 6:8; Titus 1:2).
Timothy's profession of faith, mentioned here, had clearly happened among other believers in Lystra before he set out to travel with Paul as a missionary.
