Before we can even engage in the mission of the Church we have to fight against “The delight in riches” and “desire for other things”. We must fight to cherish the kingdom above all other things – that is our first and constant battle. That is the “fight of faith”. Then when we have some experience in that basic battle we join the fight to commend the kingdom to all nations.
