'Fight' in the Bible

This command I entrust to you, Timothy, my son, in accordance with the prophecies previously made concerning you, that by them you fight the good fight,

Fight the good fight of faith; take hold of the eternal life to which you were called, and you made the good confession in the presence of many witnesses.

I have fought the good fight, I have finished the course, I have kept the faith;

You lust and do not have; so you commit murder. You are envious and cannot obtain; so you fight and quarrel. You do not have because you do not ask.
