Messianic Jews (Heb) 5:12-14

For although by this time you ought to be teachers, you need someone to teach you the very first principles of God’s Word all over again! You need milk, not solid food! Anyone who has to drink milk is still a baby, without experience in applying the Word about righteousness. But solid food is for the mature, for those whose faculties have been trained by continuous exercise to distinguish good from evil.
