1 Corinthians 9:19-23 - Sacrificing Our Liberty for the Sake of the Gospel

What did Paul mean in 1 Corinthians 9:19-23 about "becoming all things to all men"? Paul did not mean that we should water down the truth or accept practices that are contrary to scripture. Instead, he was encouraging believers to do everything for the sake of the gospel, even if it means sacrificing personal Christian liberty.
