WE should not look for peril to hit us from without.
Who is the most dangerous person on planet today?
I dont think it's Osama nor Obama.
The most dangerous people on this planet are those Who love lies,practice lies,and teach others a lie.
The most dangerous persons on planet earth are those who hold positions of authority and use them to preach "another gospel"(Gal.1:8)or better known as false teachers.
Acts 20:29-31.
I know that after I am gone,ferocious wolves will get in among you,not sparing the flock;
Even from among your own selves men will come to the front who ,by saying perverse (distorted and corrupt)things,will endeavor to draw away the diciples after them[to their own party].
therefore be always alert and on your guard,being mindful that for three years I never stopped night or day seriously to admonish and advise and exhort you one by one with tears.
2Peter2:1.
But also[in those days] there arose false prophets among the people,just as there will be false teachers among yourselves,who will subtly and stealthily introduce heretical doctrines(destructive heresies),even denying and diswning the master who bought them,bringing upon themselves swift destruction.
And many will follow their immoral ways and lascivious doings:because of them the true way will be maligned and defamed.
Jude 3-4.
Beloved,my whole concern was to write you in reguard to our common salvation.[But]I found it necessary and was impelled to write you and urgently appeal to and exhort[you]to contend for the faith which was once for all handed down to the saints[the faith which is that sum of Christian belief which was delivered verbaly to the holy people of God].
For certain men have crept in stealthily[gaining entrance secretely by a side door].their doom was predicted long ago,ungodly(impious,profane) persons who pervert the grace (the spiritual blessing and favor) of our God into lawlessness and wantonness and immorality, and disown and deny our sole Master and Lord.Jesus Christ(the Messiah,the Anointed One).
I know What Obama stands for
I know who the Jehova's witnesses are
I know all about the mormons
I know about the muslims
But what about all the false teachers
selling all the books in our churches?
