Prove all things...

1. Does it matter what one believes, so long as he is sincere?
"God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth." 2 Thess. 2:13.

NOTE.—Doctrine affects the life. Truth leads to life and God; error to death and destruction. No one would think of saying it matters not what god one worships, so long as he is sincere any more than he would think of saying it matters not what one eats or drinks, so long as he relishes what he eats and drinks; or what road he travels, so long as he thinks he is on the right road. Sincerity is a virtue; but it is not the test of sound doctrine. God wills that we shall know the truth, and He has made provision whereby we may know what is truth.

2. Did Joshua think it immaterial what God Israel served?
"Now therefore fear the Lord, and serve Him in sincerity and in truth: and put away the gods which your fathers served on the other side of the flood and in Egypt; and serve ye the Lord. And if it seem evil unto you to serve the Lord, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell : but as for me and my house, we will serve the Lord." Joshua 24:14,15.

NOTE.—The influence of all idolatrous worship is degrading. See Rom. 1:21-32; Numbers 15; 1 Cor. 10:20; 1 John 5:21.

3. How may we determine the truthfulness of any doctrine?

"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.

NOTE.—The Bible is the test of all doctrine. Whatever does not harmonize and square with this, is not to be received. "There is but one standard of the everlastingly right and the everlastingly wrong, and that is the
Bible."— T .De Witt Talmage.

5. Of what kind of doctrines should we beware?

6. What is a "wind of doctrine"?
"And the prophets shall become wind, and the word is not in them." Jer. 5:13.

10. Why did the apostle say this duty was so imperative?
"For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; and they shall turn away their ears from the truth, and shall be turned unto fables." Verses 3,4.

11. What similar instruction was given to Titus?
"But speak thou the things which become sound doctrine: . . . in all things showing thyself a pattern of good works: in doctrine showing uncorruptness, gravity, sincerity." Titus 2:1-7.

12. What will sound doctrine enable the faithful teacher to do?

13. What danger attends the teaching of false doctrine?
"Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some." 2 Tim. 2:18.

14. Who are the disciples of Jesus, and what gracious work does the truth do for those who receive it?

19. What will God allow to come to those who reject truth?
"Because they receive not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie: that they all might be damned who
believed not the truth, but had pleasure in unrighteousness." 2 Thess. 2:10-12.

20. By what doctrines are some to be misled in the last days?
"Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils." 1 Tim. 4:1. See 2 Peter 2:1.

21. What fate awaits blind teachers and their followers?
"Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch." Matt. 15:14.
