Hebrews 5:12-14

For you should already be professors instructing others by now; but instead, you need to be taught from the beginning the basics of God’s prophetic oracles! You’re like children still needing milk and not yet ready to digest solid food. For every spiritual infant who lives on milk is not yet pierced by the revelation of righteousness. But solid food is for the mature, whose spiritual senses perceive heavenly matters. And they have been adequately trained by what they’ve experienced to emerge with understanding of the difference between what is truly excellent and what is evil and harmful.
