Do not quench the Spirit; do not despise prophetic utterances. But examine everything carefully; hold fast to that which is good; abstain from every form of evil. [1 Thessalonians 5:19-22 NASB]
The Spirit is quenched when we despise prophetic utterances. Sadly, much of the church chooses to quench the Spirit of God because prophecy doesn't fit in with their doctrine, or because they are afraid it would be disruptive if people are allowed to prophesy, or they simply don't know what to do with it.
Some denominations teach that the spiritual gifts such as prophecy have been done away with, but there is no scriptural reference that says so. They most often quote Paul saying;
Love never fails; but if there are gifts of prophecy, they will be done away; if there are tongues, they will cease; if there is knowledge, it will be done away. For we know in part and we prophesy in part; but when the perfect comes, the partial will be done away. When I was a child, I used to speak like a child, think like a child, reason like a child; when I became a man, I did away with childish things. For now we see in a mirror dimly, but then face to face; now I know in part, but then I will know fully just as I also have been fully known. [1 Corinthians 13:8-12 NASB]
He says gifts of prophecy will be done away. But when? He doesn't say, "When I die," or "When the last apostle dies." He says, "when the perfect comes." I look around me and see that the world is not yet perfect. He compares the gifts of the Spirit to childish things that you put away when you grow up. We will no longer need gifts of the Spirit when we are seeing the Lord face to face. It will be perfect when we see His face.
Prophecy is an important gift of the Spirit. Don't think of prophecy as predicting the future; that is only a very small part of prophecy. Through the gift of prophecy, the church can receive direction in times of uncertainty, or comfort and encouragement in times of trial. When the church is doing well, prophecy can bring confirmation and encouragement to continue on the right path.
This doesn't mean that every so-called prophecy should be taken at face value. Rather, they should be judged. A prophecy from God will never contradict the scriptures, and it will never contradict the character of God. Prophecies are not self-serving; they are for the church, and will direct praise toward God, and not the prophet. Prophecy does not replace scripture, nor does it add to scripture.
When a prophecy is judged, then you should hold onto the good, and discard the bad. Not every person who has uttered a false prophecy is evil. Sometimes, there are well-intentioned and over-eager young Christians who haven't yet learned to fully walk in the Spirit. They should be taught and nurtured, not shunned.
On the other hand, there are wolves in sheep's clothing whose intention is to sow discord and confusion. And false prophecy is a favorite tool. If they cannot be taught, they should be shunned and avoided because they are false prophets.
Church leaders - I urge you to encourage prophecy. The member who sits quietly, and doesn't speak, may have prophetic word from God. But he may never speak it if he is afraid of your reaction.
Church members - don't despise prophetic words, but test them. If you think you have a prophetic word, test it yourself before you speak. Don't be disruptive or contentious. You have the choice to speak or not, and you have the choice of when and how to speak. As Paul said;
and the spirits of prophets are subject to prophets; for God is not a God of confusion but of peace, as in all the churches of the saints. [1 Corinthians 14:32-33 NASB]
Prophecy shouldn't be despised because it comes from a common church member. Nor should it be accepted without question if it comes from a minister. All prophecy should be judged equally against the word of God.
Thank You, Father, that Your gifts are still operating in the world. I pray for discernment to know true prophecy, and separate it from the false.
