soldier

Concise Bible Dictionary:

Apart from the common application of this term (for which see ARMY, Armor, &c.) it is used in the New Testament for the service of a Christian. Two things are said of the Christian soldier. He must “endure hardness,” that is, share in the suffering incident to warfare; and he must not entangle “himself with the affairs of this life, that he may please him who hath chosen him to be a soldier”; that is, be quite free to obey his Captain in all things. As explained by the centurion, “I say to this man Go, and he goeth; and to another, Come, and he cometh;” so the Christian servant is under authority, and unhesitating obedience is what should characterize the soldier of Jesus Christ: he must be prepared to endure hardships, and to suffer with his Captain (Matt. 8:99For I am a man under authority, having soldiers under me: and I say to this man, Go, and he goeth; and to another, Come, and he cometh; and to my servant, Do this, and he doeth it. (Matthew 8:9); 2 Tim. 2:3-43Thou therefore endure hardness, as a good soldier of Jesus Christ. 4No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier. (2 Timothy 2:3‑4)).
