In Philippians 2:25[1] and Philemon 1:2,[2]Paul describes fellow Christians as "fellow soldiers" (in Greek, συστρατιώτῃ, sustratiōtē).[3] The image of a soldier is also used in 2 Timothy 2:3–4[4] as a metaphor for courage, loyalty and dedication;[5] this is followed by the metaphor of an athlete, emphasising hard work. In 1 Corinthians 9:7,[6] this image is used in a discussion of church workers receiving payment, with a metaphorical reference to a soldier's rations and expenses.[7]
^2 Timothy 2:3–4, NIV (BibleGateway): "Endure hardship with us like a good soldier of Christ Jesus. No one serving as a soldier gets involved in civilian affairs—he wants to please his commanding officer."
