1,330. The Power of Words
207:3 A person should never say things like "I wasn't punished enough for my sins" because doing so provides an opening for the Heavenly accuser.
207:4 One shouldn't tell a mourner things like, "What are you going to do? You can't change what G-d decides." This is tantamount to blasphemy because it suggests that if it were possible, he would change it. Rather a person must accept G-d's decree upon himself with love.
