Hebrews 12:4-8

4You have not yet resisted to bloodshed, striving against sin.

5And 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;

6For whom the Lord loves He chastens, And scourges every son whom He receives.”

7If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten?

8But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons.
