"Brothers, do not be children in your thinking. Be infants in evil, but in your thinking be mature....If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, will they not say that you are out of your minds? ....So my brother, earnestly desire to prophesy, and do not forbid speaking in tongues. But all things should be done decently and in order." 1 Corinthians 14:20, 23, 39
"the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons….In pointing out these things to the brethren, you will be a good servant of Christ Jesus, constantly nourished on the words of the faith and of the sound doctrine which you have been following." ~ 1 Timothy 4:1, 6
