'Defeated' in the Bible

The fact that you have lawsuits among yourselves demonstrates that you have already been defeated. Why not rather be wronged? Why not rather be cheated?

For if, having escaped the world’s impurity through the knowledge of our Lord and Savior Jesus Christ, they are again entangled in these things and defeated, the last state is worse for them than the first.

Little children (believers, dear ones), you are of God and you belong to Him and have [already] overcome them [the agents of the antichrist]; because He who is in you is greater than he (Satan) who is in the world [of sinful mankind].

but they were not strong enough and did not prevail, and there was no longer a place found for them in heaven.
