Warnock employs a common liberal ploy where he takes a well-known verse from the Bible, Matthew 6:24 in this case, where Jesus clearly states that man cannot serve God and mammon, and changes it to mean whatever suits his own purposes at the time. A very easy internet search would show anyone who isn’t familiar with the term mammon that it basically means material wealth. You don’t need a seminary education to know that Warnock is taking this verse wildly out of context.
To compare the sacrifice of men and women in a US uniform to a sinful desire for material gain maaaaaaaaay not be so popular in a southern state like Georgia.
