Hebrews 12:5-8

5and ye have forgotten the exhortation, which reasoneth with you as with sons, My son, regard not lightly the chastening of the Lord, Nor faint when thou art reproved of him;

6For whom the Lord loveth he chasteneth, And scourgeth every son whom he receiveth.

7It is for chastening that ye endure; God dealeth with you as with sons; for what son is there whom his father chasteneth not?

8But if ye are without chastening, whereof all have been made partakers, then are ye bastards, and not sons.
