Contemporary psychology tells us that there are two qualities that make for psychological health and well being. A person being open/vulnerable about themselves and being open to feedback/constructive criticism.
The Bible told us that long before modern psychology. James 5:6 says ” Confess your faults one to another”. That’s about us being willing to be open/vulnerable about our faults, failures and fears.
Psalm 141 talks about being open to feedback/constructive criticism. Verse 5 says:
5 Let the righteous strike me;
It shall be a kindness.
And let him rebuke me;
It shall be as excellent oil;
Let my head not refuse it.
We all need righteous people in our lives who will “strike us”, people we respect who love us who will speak into our lives and help us see our blind spots so we can grow. We live in a culture and society where it is politically incorrect to tell another person their faults or weaknesses, but the truth is some of our faults we will never see without the help of others.We should welcome the feedback of “the righteous”. As the psalmist says such a rebuke is “as excellent oil”.
Oil in the Old Testament was used to consecrate the priests, to set them apart to serve God. The more we will be open and willing to receive the “rebuke of the righteous” the more it will set us apart, position and equip us to serve God more effectively.
That sort of rebuke is a real blessing.
