He that is of God heareth God's words: ye therefore hear them not, because ye are not of God. - John 8:47

My son, if thou wilt receive my words, and hide my commandments with thee; 2 So that thou incline thine ear unto wisdom, and apply thine heart to understanding; 3 Yea, if thou criest after knowledge, and liftest up thy voice for understanding; 4 If thou seekest her as silver, and searchest for her as for hid treasures; 5 Then shalt thou understand the fear of the Lord, and find the knowledge of God. - Proverbs 2:1-5

And he said unto them, Take heed what ye hear: with what measure ye mete, it shall be measured to you: and unto you that hear shall more be given - Mark 4:24
