yet in a church I desire to speak five words with my mind, so that I might also teach others, than ten thousand words in a tongue.
Brothers, do not be children in your minds, but in malice be like infants, and in your minds be mature.
(1Co 14:19-20)
And I, brothers, could not speak to you as to spiritual ones, but as to fleshly, as to babes in Christ. I have fed you with milk and not with solid food, for you were not yet able to bear it; nor are you able even now.
For you are yet carnal. For in that there is among you envyings and strife and divisions, are you not carnal, and do you not walk according to men?
(1Co 3:1-3)
