(KJV) Matthew
7:6 'Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.'
7:20 'Wherefore by their fruits ye shall know them.'
7:21 'Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.'
24:24 'For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.'
False prophets will abound, as will false Christians.
Amen! This is getting fun!
