Hebrews 12:3-6 (NKJV)
3 For consider Him who endured such hostility from sinners against Himself, lest you become weary and discouraged in your souls.
4 You have not yet resisted to bloodshed, striving against sin.
5 And you have forgotten the exhortation which speaks to you as to sons:

“My son, do not despise the chastening of the LORD,
Nor be discouraged when you are rebuked by Him;
6 For whom the LORD loves He chastens,
And scourges every son whom He receives.”
