1 Thessalonians 5:19-22

Do not quench (suppress or subdue) the [Holy] Spirit; Do not spurn the gifts and utterances of the prophets [do not depreciate prophetic revelations nor despise inspired instruction or exhortation or warning]. But test and prove all things [until you can recognize] what is good; [to that] hold fast. Abstain from evil [shrink from it and keep aloof from it] in whatever form or whatever kind it may be.
