The Mind. Are you building strongholds?

The Bible is very clear that we are to take thoughts captive, those thoughts that stand against the very knowledge of God. But are we? Gas prices, eggs, interest rates, viruses, attacks from enemies, inflation, tariffs, family, health, oh my God what ever will we do?  Satan is using your own thoughts to hire you to build strongholds or prisons in your own mind! Do we have an answer for the times we live in? OR are we just subject to whatever this world tosses our way? How does one renew the mind? Lets talk about it.
