Over emphasis of self righteousness most often hinders self sacrifice and service to others.
“What sorrow awaits you teachers of religious law and you Pharisees. Hypocrites! For you are careful to tithe even the tiniest income from your herb gardens, but you ignore the more important aspects of the law—justice, mercy, and faith. You should tithe, yes, but do not neglect the more important things. Blind guides! You strain your water so you won’t accidentally swallow a gnat, but you swallow a camel!
~ Jesus according to Matthew 23:22-24
