You have to rember that the parisee had an outward form of godilness but inwardly was full of dead mens bones, Jesus said of the scribes that they made the way to God difficult. We are only changed as we see Jesus, we go from glory to glory. As a minister, or preacher if you will, if I can't bring a clear picture of who Jesus is, or what His doctrine is, lifting Him high in the sight of the congregation, than I have failed.
And what is the false holiness he is reffering to?
It's a man centered attempt at becoming holy. Usually has a strong outward code or ethic in dress as well as disposition. Instead of saying that one should dress modestly and allowing the Holy Spirit to bring a sense of personal conviction, we say dress modestly and this how and what you wear and how you dress in order to fit in and show that you are holy. The same is true about disposition, we say be gentle, humble, kind...etc...these are the workings of the Holy Spirit, His fruit, humility is nothing more than perfect yeildedness to the Spirit of the Living God in obedience. But we tell people "if you act a certain way than you are humble" and so the list goes on. The false holiness revival is a manward attempt at being holy. Like Paul said in Galatians,O'foolish galatians having begun in the spirit are you now made pefect in the flesh?And I know he was talking circumcision, however the principle is the same.
The narrow path that Jesus was talking about was was a life fully devoted to beholding Him and following Him, the change that occurs in us happens very naturally as we look upon Him.
