1 Timothy 6:3-5 If anyone teaches otherwise and does not consent to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which accords with godliness, 4he is proud, knowing nothing, but is obsessed with disputes and arguments over words, from which come envy, strife, reviling, evil suspicions, 5 useless wranglings of men of corrupt minds and destitute of the truth, who suppose that godliness is a means of gain. From such withdraw yourself.
Acts 28:27 for the hearts of this people have grown dull. Their ears are hard of hearing, And their eyes they have closed, lest they should see with their eyes and hear with their ears, lest they should understand with their hearts and turn, So that I should heal them.
