Mysterious Confession of Freedom (1 Timothy 4:1-5)

Paul tells us that Godliness is a mystery in 1 Timothy 3:16.  Saying that Godliness is a mysteryis a pretty profound statement because Paul is encouraging Timothy to stand against agitators in Ephesus.  How can such a statement encourage Timothy?  How can such a statement help Timothy refute the false teaching that is entering the church?  So, what happens if we lose sight of Christ being our life blood and nourishing us in our redemption?  What happens if we fail to see that Godliness is a mystery?
