1 Corinthians 14:36-15:2
36 Or did the word of God originate with you? Or are you the only people it has reached? 37 If anyone thinks they are a prophet or otherwise gifted by the Spirit, let them acknowledge that what I am writing to you is the Lord’s command. 38 But if anyone ignores this, they will themselves be ignored.
39 Therefore, my brothers and sisters, be eager to prophesy, and do not forbid speaking in tongues. 40 But everything should be done in a fitting and orderly way.
15 Now, brothers and sisters, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. 2 By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
