4:1 I therefore, a prisoner for the Lord, urge you to walk in a manner worthy of the calling to which you have been called, 2 with all humility and gentleness, with patience, bearing with one another in love, 3 eager to maintain the unity of the Spirit in the bond of peace.
24 Whoever spares the rod hates his son,
but he who loves him is diligent to discipline him. 
18 “If a man has a stubborn and rebellious son who will not obey the voice of his father or the voice of his mother, and, though they discipline him, will not listen to them, 19 then his father and his mother shall take hold of him and bring him out to the elders of his city at the gate of the place where he lives, 20 and they shall say to the elders of his city, ‘This our son is stubborn and rebellious; he will not obey our voice; he is a glutton and a drunkard.’ 21 Then all the men of the city shall stone him to death with stones. So you shall purge the evil from your midst, and all Israel shall hear, and fear.
5 And have you forgotten the exhortation that addresses you as sons?
“My son, do not regard lightly the discipline of the Lord,
nor be weary when reproved by him.
6 For the Lord disciplines the one he loves,
and chastises every son whom he receives.”
7 It is for discipline that you have to endure. God is treating you as sons. For what son is there whom his father does not discipline? 8 If you are left without discipline, in which all have participated, then you are illegitimate children and not sons.
6 Likewise, urge the younger men to be self-controlled.
8 Hear, my son, your father's instruction,
and forsake not your mother's teaching,
9 for they are a graceful garland for your head
and pendants for your neck.
34 A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. 35 By this all people will know that you are my disciples, if you have love for one another.” (ESV)
