James, I went right to the end after this thread seemed to go astray, so someone else might have pointed this out so here is my take on your inquiry: God has a reason for chastising His children:
To modify their behavior so that He can bless and reward them
in this life:
Hebrews 12:11 Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.
The fruit of righteousness is its own reward.
