PROVE ALL THINGS
From the time of Paul and Timothy, evil men and seducers have gained strength and influence because their congregations love their flatteries and lies. (Today, most people don't want to hear sermons about sin and its punishment --or that Jesus will deliver them from their sins. Instead, they want to keep their sins and hear the reassuring words of the serpent: "Ye shall not surely die.")
For the sincere in heart, it is vital that we put all teaching under the light of the scriptures and prove all things --even doctrines that have been considered orthodox for centuries. Some churchmen have accepted doctrines of demons because they have not tested the source of supernatural signs and wonders.
Supernatural signs and wonders do not authenticate a teaching. Here, the prophet Isaiah has given us a standard that will expose many of the false teachers in todays churches:
"To the law and to the testimony: if they speak not according to this word, it is because there is no light in them." Isa 8:20
"And the dragon was wroth with the woman, and went to make war with the remnant of her seed, WHICH KEEP THE COMMANDMENTS OF GOD, AND HAVE THE TESTIMONY OF JESUS CHRIST." Rev 12:17 (KJV)
