5:11 On this topic we have much to say 1 and it is difficult to explain, since you have become sluggish 2 in hearing. 5:12 For though you should in fact be teachers by this time, 3 you need someone to teach you the beginning elements of God’s utterances. 4 You have gone back to needing 5 milk, not 6 solid food. 5:13 For everyone who lives on milk is inexperienced in the message of righteousness, because he is an infant. 5:14 But solid food is for the mature, whose perceptions are trained by practice to discern both good and evil.
