1 Thessalonians 5:
19 Do not put out the Spirit's fire;
20 do not treat prophecies with contempt.
21 Test everything. Hold on to the good.
Compared to:
Jeremiah 24:2
One basket had very good figs, like those that ripen early; the other basket had very bad figs, so bad they could not be eaten.
If there is a need to say, from that above it may be thought that when reading explanations of scripture a person should separate the parts that are true from the parts that are false in the explanations and "Hold on to the good." and that there should be no biased judgement.
What may you think after looking at what you may look at below ?
"Wherefore said He not, “but he that doeth my will?” Because for the time it was a great gain for them to receive even this first; yea it was very great, considering their weakness. And moreover He intimated the one also by the other. And withal this may be mentioned, that in fact there is no other will of the Son besides that of the Father.
And here He seems to me to be censuring the Jews chiefly, laying as they did the whole stress upon the doctrines, and taking no care of practice. For which Paul also blames them, saying, “Behold thou art called a Jew, and restest in the law, and makest thy boast of God, and knowest His will:” “Who then are these men?” you ask. Many of them that believed received gifts such as he that was casting out devils, and was not with Him; such as Judas; for even he too, wicked as he was, had a gift. And in the Old Testament also this may be found, in that grace hath oftentimes wrought upon unworthy persons, that it might do good to others. That is, since all men were not meet for all things, but some were of a pure life, not having so great faith, and others just the contrary; by these sayings, while He urges the one to show forth much faith, the others too He was summoning by this His unspeakable gift to become better men. Wherefore also with great abundance did He bestow that grace. For “we wrought,” it is said, “many mighty works.” But “then will I profess unto them, I knew you not.” For “now indeed they suppose they are my friends; but then shall they know, that not as to friends did I give to them.”
And why marvel if He hath bestowed gifts on men that have believed on Him, though without life suitable to their faith, when even on those who have fallen from both these, He is unquestionably found working? For so Balaam was an alien both from faith and from a truly good life; nevertheless grace wrought on him for the service of other men. And Pharaoh too was of the same sort: yet for all that even to him He signified the things to come. And Nebuchadnezzar was very full of iniquity; yet to him again He revealed what was to follow after many generations. And again to the son of this last, though surpassing his father in iniquity, He signified the things to come, ordering a marvellous and great dispensation. Accordingly because then also the beginnings of the gospel were taking place, and it was requisite that the manifestation of its power should be abundant, many even of the unworthy used to receive gifts. Howbeit, from those miracles no gain accrued to them; rather they are the more punished. Wherefore unto them did He utter even that fearful saying, “I never knew you:” there being many for whom His hatred begins already even here; whom He turns away from, even before the judgment.
Let us fear therefore, beloved; and let us take great heed to our life, neither let us account ourselves worse off, in that we do not work miracles now. For that will never be any advantage to us, as neither any disadvantage in our not working them, if we take heed to all virtue. Because for the miracles we ourselves are debtors, but for our life and our doings we have God our debtor.
3. Having now, you see, finished all, having discoursed accurately of all virtue, and pointed out the pretenders to it, of divers kinds, both such as for display fast and make prayers, and such as come in the sheep’s hide; and them too that spoil it, whom He also called swine and dogs: He proceeds to signify how great is the profit of virtue even here, and how great the mischief of wickedness, by saying,
“Whosoever therefore heareth these sayings of mine, and doeth them, shall be likened unto a wise man.”
As thus: What they shall suffer who do not (although they work miracles), ye have heard; but ye should know also what such as obey all these sayings shall enjoy; not in the world to come only, but even here. “For whosoever,” saith He, “heareth these sayings of mine, and doeth them, shall be likened to a wise man.”
Seest thou how He varies His discourse; at one time saying, “Not every one that saith unto me, Lord, Lord,” and revealing Himself; at another time, “He that doeth the will of my Father;” and again, bringing in Himself as judge, “For many will say to me in that day, Lord, Lord, have we not prophesied in thy name, and I will say, I know you not.” And here again He indicates Himself to have the power over all, this being why He said, “Whosoever heareth these sayings of mine.”"
