'Fighting' in the Bible

This order I give to you, Timothy my son, in harmony with the words of the prophets about you, so that by them you may be strong, fighting the good fight,

And this is the purpose of all our work and our fighting, because our hope is in the living God, who is the Saviour of all men, and specially of those who have faith.

He has an over-high opinion of himself; being without knowledge, having only an unhealthy love of questionings and wars of words, from which come envy, fighting, cruel words, evil thoughts,

Be fighting the good fight of the faith; take for yourself the life eternal, for which you were marked out, and of which you gave witness in the eyes of all.
