To the pure all things are pure;
but to those who are defiled and unbelieving,
nothing is pure, but both their mind
and their conscience are defiled.
They profess to know God,
but by their deeds they deny Him,
being detestable and disobedient
and worthless for any good thing.
Behavior is of unsurpassed importance in the Christian way.
"A Model of Christian Maturity"
Several years ago there was a pop group named Milli Vanilli and they were riding the crest of popularity until it was discovered that they were not the ones actually singing, but that they were lip-syncing their music. They did not posses the talent they professed to have. Great showmen, yes. Looked the part...cool and hip, absolutely. Said all the right things, of course. But it was discovered they were not really what they professed to be.
There is and always has been those who lip-sync their faith, who say the right things and look the part when they are in front of the Christian crowd, but are eventually given away by their behavior, by the actual things that they say, do, and participate in on a consistent basis. You see, you really do live out what you believe. In fact, it is impossible to do otherwise.
