2 Timothy 2:4: No one serving as a soldier gets involved in civilian affairs—he wants to please his commanding officer.

Paul describes the believer as one who is a "soldier" for Christ. (Christ is our commanding officer). The soldier doesn't get involved in civilian affairs. He dedicates himself to the commands and wishes of his commander. So, what are civilian affairs? It's interesting that the greek word translated to civilian affairs is bios which means daily life or existence day to day. So, Paul is saying have a weak hold on the things of earthly life. Abandon all that is worldly for the wishes of Jesus. To allow Christ to be my Lord, I must hold loosely to all things temporal and spontaneously respond immediately to all Christ's directives.
