Are Christians Expected to "Endure unto the End?"

Bible teaching is crystal clear: Jesus expects us to continue in the "narrow way" and endure through His power, the Holy Ghost within us, to the very end. 33% of the New Testament is ignored by the seminary-bible school industrial complex, as evidenced by the beta preachers we have to put up with - who actually believe obedience is optional and weaken the people of God. Thus, zero spiritual power in the modern Western church.
